iii-v wafers

 

WE HAVE THE FOLLOWING III-V WAFERS IN STOCK GAAS, GASB, GAP, INAS, INSB


III-V semiconductors are great for optoelectronic use. III-V crystallize with high degree of stoichiometry.

We have both n-type and p-type. Our III-V wafers have high carrier mobilities and direct energy gaps.


What are III-V wafers used for?

Gallium Arsenide (GaAs)

second most common in use after silicon, commonly used as substrate for other III-V semiconductors, e.g. InGaAs and GaInNAs. Brittle. Lower hole mobility than Si, P-type CMOS transistors unfeasible. High impurity density, difficult to fabricate small structures. Used for near-IR LEDs, fast electronics, and high-efficiency solar cells. Very similar lattice constant to germanium, can be grown on germanium substrates.

Gallium Animonide (GaSb)

Used for infrared detectors and LEDs and thermophotovoltaics. Doped n with Te, p with Zn.

Indium Phosphide (InP)

Commonly used as substrate for epitaxial InGaAs. Superior electron veloxity, used in high-power and high-frequency applications. Used in optoelectronics.

Indium Arsenide (InAs)

Used for infrared detectors for 1â€"3.8 µm, cooled or uncooled. High electron mobility. InAs dots in InGaAs matrix can serve as quantum dots. Quantum dots may be formed from a monolayer of InAs on InP or GaAs. Strong photo-Denber emitter, used as a terahertz radiation source.
