P Type , High Purity Single Crystal Indium Phosphide Wafer , 4”, Prime Grade

PAM-XIAMEN manufactures high purity single crystal Indium Phosphide Wafers for optoelectronics applications. Our standard wafer diameters range from 25.4 mm (1 inch) to 200 mm (6 inches) in size; wafers can be produced in various thicknesses and orientations with polished or unpolished sides and can include dopants. PAM-XIAMEN can produce wide range grades: prime grade, test grade, dummy grade, technical grade, and optical grade. PAM-XIAMEN also offer materials to customer specifications by request, in addition to custom compositions for commercial and research applications and new proprietary technologies.

What is InP wafer?

Indium phosphide is a semiconducting material similar to GaAs and silicon but is very much a niche product. It’s very effective at developing very high-speed processing and is more expensive than GaAs because of the great lengths to gather and develop the ingredients. Let’s take a look at some more facts about indium phosphide as it pertains to an InP Wafer.

Transport Properties in High Electric Fields

	Field dependences of the electron drift velocity in InP, 300 K. Solid curve are theoretical calculation. Dashed and dotted curve are measured data. (Maloney and Frey [1977]) and (Gonzalez Sanchez et al. [1992]).
	The field dependences of the electron drift velocity for high electric fields. T(K): 1. 95; 2. 300; 3. 400. (Windhorn et al. [1983]).
	Field dependences of the electron drift velocity at different temperatures. Curve 1 -77 K (Gonzalez Sanchez et al. [1992]). Curve 2 - 300 K, Curve 3 - 500 K (Fawcett and Hill [1975]).
	Electron temperature versus electric field for 77 K and 300 K. (Maloney and Frey [1977])
	Fraction of electrons in L and X valleys nL/no and nX/no as a function of electric field, 300 K. (Borodovskii and Osadchii [1987]).
	Frequency dependence of the efficiency η at first (solid line) and at the second (dashed line) harmonic in LSA mode. Monte Carlo simulation. F = Fo + F1·sin(2π·ft) + F2·[sin(4π·ft)+3π/2], Fo=F1=35 kV cm-1, F2=10.5 kV cm-1 (Borodovskii and Osadchii [1987]).
	Longitudinal (D || F) and transverse (D ⊥ F) electron diffusion coefficients at 300 K. Ensemble Monte Carlo simulation. (Aishima and Fukushima [1983]).
	Longitudinal (D || F) and transverse (D ⊥ F) electron diffusion coefficients at 77K. Ensemble Monte Carlo simulation. (Aishima and Fukushima [1983]).

Optoelectronic Applications

InP based lasers and LEDs can emit light in the very broad range of 1200 nm up to 12 µm. This light is used for fibre based Telecom and Datacom applications in all areas of the digitalised world. Light is also used for sensing applications. On one hand there are spectroscopic applications, where a certain wavelength is needed to interact with matter to detect highly diluted gases for example. Optoelectronic terahertz is used in ultra-sensitive spectroscopic analysers, thickness measurements of polymers and for the detection of multilayer coatings in the automotive industry. On the other hand there is a huge benefit of specific InP lasers because they are eye safe. The radiation is absorbed in the vitreous body of the human eye and cannot harm the retina. InP lasers in LiDAR (Light Detection And Ranging) will be a key component for the mobility of the future and the automation industry.
