We have the following III-V wafers in stock GaAs, GaSb, GaP, InAs, InSb

 

III-V Wafers

 


 

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 Phosphide (GaP)

Used in early low to medium brightness cheap red/orange/green LEDs. Used standalone or with GaAsP. Transparent for yellow and red light, used as substrate for GaAsP red/yellow LEDs. Doped with S or Te for n-type, with Zn for p-type. Pure GaP emits green, nitrogen-doped GaP emits yellow-green, ZnO-doped GaP emits red.

 

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.
