Nanostructures are materials or devices with at least one dimension between 1 and 100 nanometers. At this scale, materials often exhibit unique electrical, optical, magnetic, thermal, and mechanical properties that differ significantly from their bulk counterparts. These characteristics make nanostructures essential for next-generation electronics, photonics, energy devices, biomedical engineering, and quantum technologies.
Researchers fabricate nanostructures using advanced techniques such as physical vapor deposition (PVD), chemical vapor deposition (CVD), electron beam lithography (EBL), photolithography, sputtering, reactive ion etching (RIE), and atomic layer deposition (ALD).
The substrate plays a critical role in nanostructure performance by affecting crystal quality, thermal conductivity, optical transmission, electrical behavior, and fabrication compatibility. The most common research substrates include:
| Substrate | Typical Applications |
|---|---|
| Silicon | MEMS, CMOS, photonics, sensors, nanowires |
| Silicon-on-Insulator (SOI) | E-beam lithography, MEMS, photonic devices |
| Sapphire | GaN growth, LEDs, optical devices |
| Silicon Carbide (SiC) | Power electronics, harsh-environment sensors |
| Gallium Arsenide (GaAs) | High-speed electronics and RF devices |
| Fused Silica & Quartz | Optics, photonics, UV applications |
| Graphene & 2D Materials | Flexible electronics and quantum devices |
