INDIUM PHOSPHIDE (InP) WAFERS are semiconductor materials made of indium phosphide, a compound semiconductor that is widely used in high-frequency and optoelectronic applications. Due to its efficient electron mobility and direct bandgap properties, InP is favored for devices such as:
High-speed electronics
Laser diodes
Photodetectors
Telecommunications applications, including optical fiber communication
We offer the following InP Wafers:
Undoped InP Wafers: These are pure InP with no intentional doping, used in various applications where intrinsic properties are required.
N-type InP Wafers: Doped with donor impurities (such as tellurium) to increase electron concentration, useful in transistors and high-speed electronics.
P-type InP Wafers: Doped with acceptor impurities (such as zinc) to create holes in the semiconductor, used in light-emitting devices and other optoelectronics.
InP Substrates: Used as a base for growing other semiconductor materials in heterostructures for various applications.
InP Membrane Wafers: Thin layers of InP used for specific applications, including applications in flexible electronics and advanced photonic devices.
