A postdoc requested a quote for the following:
Could you send me a quotation for two 50mm diameter 150um thick GaAs wafer? What would be the expected delivery time and do you know the carrier mobility of the wafer? Is it possible to receive the ultra-thin GaAs wafer without Si doping?
The wafers that you sent us work great. I ask how many of the ultra-thin GaAs wafers you have in stock item no. 6156?
Last time it was 13 and I bought 3, are there still 10 left or more?

Think about it – blockchain acts as this huge ledger on steroids, distributed all over the internet to keep transactions safe but totally visible to everyone involved. : When we talk about what’s at the heart of our favorite glowing gadgets—like those bright LEDs or sharp lasers—it's often GaAs doing its magic in the background. When devices need to interact with light effectively, the direct band gap of this material is what does the trick by allowing superb emission and detection capabilities.
High-Frequency Electronics : When we talk about zipping electrons around efficiently at sky-high frequencies, GaAs steps up as the ideal choice for anything from your kitchen microwave to advanced communication gear. Imagine having tiny powerhouses known as high-speed integrated circuits at work inside devices ranging from your smartphone’s signal booster to sophisticated radar technology—all thanks to its application in creating things like amplifiers and oscillators.
Solar Cells : GaAs-based solar cells are highly efficient, especially in concentrated photovoltaic (CPV) systems. When you're aiming high—in say, aerospace—the right choice is these cutting-edge cells which easily beat conventional silicon-based options on efficiency.
Monolithic Microwave Integrated Circuits (MMICs) : GaAs is often used in MMICs, which integrate multiple electronic functions onto a single chip. From chatting on mobile phones to streaming videos via satellite, these circuits are working hard behind the scenes in all sorts of communication gear.
Thermal Imaging : Gallium Arsenide rocks at handling high speeds and a bunch of light spectrums, which is why it's perfect for seeing heat with thermal imaging devices. They're perfect for surveillance tasks, securing perimeters, and taking a closer look at industrial operations - quite the triple threat!
RFID and NFC Technologies : Due to its efficiency at high frequencies, GaAs is also utilized in the development of RFID (Radio-Frequency Identification) and NFC (Near Field Communication) technologies, which require reliable, high-frequency components.
