Researcher: Ultrathin BaF2 films

" I had to explain to him that a thin film of barium fluorides with different thicknesses was deposited on GaAs substrate by electron beam evaporation. The aim of the work was to identify the best growth conditions for the production of coatings with a low work function suitable for the anode of hybrid thermionic-photovoltaic (TIPV) devices. The chemical composition and work function ϕ of the films with different thicknesses were investigated by X-ray photoelectron spectroscopy (XPS) and ultraviolet photoelectron spectroscopy (UPS). The lowest value of ϕ = 2.1 eV was obtained for the film with a thickness of ~2 nm. In the valence band spectra of the films at low kinetic energy, near the cutoff, a characteristic peak of negative electron affinity was present. This effect contributed to a further reduction of the film's work function. In 2007, I was involved in a project to develop a new type of solar cell based on nanostructured barium strontium titanate (BST) thin films deposited on Si substrates by pulsed laser deposition (PLD)."

Barium Fluoride (BaF2) Work functionThermionic-thermo photovoltaic energy conversion Ultraviolet photoemission spectroscopy

Electron Beam Evaporation was used to analyze the deposition of ultra-thin Barium Fluoride (BaF2) films on gallium arsenide wafers. Film thickness and chemical composition on the work function of the resulting heterostructure. X-ray photoemission spectroscopy combined with ultraviolet photoemission spectroscopy measurements reveals that films of 2 nm nominal thickness and Ba/F = 1.0 stoichiometry ratio induce the achievement of a significantly low work function of 2.1 eV to the BaFx/GaAs heterostructure. The significant reduction of the work function at least down to 3.0 eV is confirmed by a test thermionic converter operating at a cathode temperature of 1385 °C, where the heterostructure was applied as anode. The low work function, together with a negligible optical absorption, makes feasible the practical application of barium fluoride coatings on GaAs within hybrid thermionic-thermophotovoltaic devices.

What Is Barium Fluoride (BaF2) Used For?

Barium fluoride is a common mineral found in soils, rocks, and minerals. It is also an excellent optical coating and is transparent to infrared light. Because it is non-reactive, it is commonly used for optical components, such as lenses. It is used in thermography as a viewport window because of its high transmission range and excellent thermal shock resistance. Its use in nuclear physics and Positron Emission Tomography applications is also growing.

This chemical compound is used in various industries, including in the production of enamel and glazing frits. It is also used as a welding agent, which is why it is listed on the Canadian Domestic Substances List (CDS). It is used as a molten bath in the refining of aluminum, but it should not be exposed to X-rays as this material will decompose and emit toxic fumes.

Barium fluoride is a chemical that is highly reactive with aqueous solutions of ammonium chloride. It is transparent from ultraviolet to infrared and has a wide range of uses. It is used in ceramic flux and as a preopacifying agent in glass and porcelain. It is also a component of some welding powders and rods. It is a common component of aluminum and can be used to refine the metal.

Because it glows in ultraviolet light, barium fluoride is a useful scintillator. It is one of the fastest detectors, and is very sensitive to heat. It is useful in detecting 511 keV gamma photons in positron emission tomography. It is also used to separate high-energy neutrons. In addition to preventing the decay of aluminum, it can be used to make a viewport window for thermal imaging.

It is often used in spectroscopic components and as a viewport window in thermography. Its transmission range is a micron longer than calcium fluoride. It is also more sensitive to thermal shock than calcium fluoride. The material is used in a variety of other applications. Its toxicity is moderate, but it is not harmful to humans in small quantities. In fact, it is often considered one of the safest substances for electrochromic glasses.

Although barium fluoride is not a flammable substance, it is highly corrosive when exposed to humidity or moisture. It is also susceptible to X-rays and should be used with caution. In some instances, it is a highly-purified alloy. However, its toxic nature makes it unsuitable for vacuum environments. Nevertheless, barium fluoride is a good candidate for electrochromic filters.

Barium fluoride is a chemical compound that is very stable and highly resistant to sunlight. It is used in glass, and it is safe to work with a wide range of other materials. The only thing it does not like is humidity. Its main use is in optical components. While this mineral can be corroded under vacuum, it can be cured with ultraviolet light. This makes barium fluoride a great candidate for electrochromic devices.

The mineral barium fluoride is used as a preopacifying agent. It is also used in the manufacture of enamel and glazing frits. It is a good welding agent. It is also an additive in some fluxes. It is widely used in the production of aluminium. If you are unsure of what is Barium fluoride used for, it's important to understand its uses.

Barium fluoride is used in spectroscopic components. It is especially useful in the IR band. Its high transmission range and resistance to thermal shock makes it a great material for thermography. Further, barium fluoride is much more durable than calcium fluoride and is more suitable for use in high-energy physics experiments.

Barium Fluoride Sputtering Targets

BaF2 thin films are sputtered on aluminum, silicon and glass solid substrates using electron beam evaporation (EBE) technique in vacuum (6 to 10 mbar) and at room temperature. The thickness of the barium fluoride deposited thin layer on the substrates mentioned above is nearly 20nm with a deposition rate of 0.4 to 0.5 nm per second. In the sputtering process, all substrates are precisely cleaned before depositing the BaF2. A quartz crystal is applied to monitor the thickness. After the deposition, the surface structure is characterized by Glancing Angle X-ray Diffraction (GAXRD) diffractometer. Atomic force microscopy is used to study the morphology of the thin film. According to the characterization data by XRD peaks, the crystallites size on silicon substrate appears to be remarkably smaller than aluminum and glass substrates. The thin film prepared in this way has numerous physical and chemical specifications so qualified enough to be applied in manufacturing high-tech microprocessors.

What is Barium Fluoride?

Inorganic compound with the formula BaF2, barium fluoride is found naturally in the rare mineral frankdicksonite. Under standard conditions, it takes on the structure of a fluorite. Under high pressure, it adopts that of PbCl2. Because it is resistant to water, it is insoluble in it. However, it is highly corrosive and is dangerous for humans.

Infrared BaF2 optical components have different shapes. Some are rods, while others are wedges or prisms. Some have cylindrical and spherical shapes. The shape of these optical components is very important for the efficiency of the device. They must be made from glass that is not contaminated by other substances. This is essential when it comes to safety, and the use of this material must be limited.

IR thermography is one of the most common uses of barium fluoride. It is transparent and is effective in separating rhodamine B from methylene blue. Its applications in this field are numerous and have a promising future for the development of new in-situ TLC/FTIR analysis techniques. So, it's time to take advantage of this mineral! What's It Like?

The fast and slow parts of the emission of the chemical substance are essentially the same. They are not related to each other.
