N Type , InP(Indium Phosphide) Substrate,3”, Prime Grade -Compound Semiconductor

PAM-XIAMEN offers InP wafer – Indium Phosphide which are grown by LEC(Liquid Encapsulated Czochralski) or VGF(Vertical Gradient Freeze) as epi-ready or mechanical grade with n type, p type or semi-insulating in different orientation(111)or(100).

Indium phosphide (InP) is a binary semiconductor composed of indium and phosphorus. It has a face-centered cubic (“zinc blende”) crystal structure, identical to that of GaAs and most of the III-V semiconductors.Indium phosphide can be prepared from the reaction of white phosphorus and indium iodide[clarification needed] at 400 °C.,[5] also by direct combination of the purified elements at high temperature and pressure, or by thermal decomposition of a mixture of a trialkyl indium compound and phosphide. InP is used in high-power and high-frequency electronics[citation needed] because of its superior electron velocity with respect to the more common semiconductors silicon and gallium arsenide.

What is a Test Wafer?

Most test wafers are wafers which have fallen out of prime specifications. Test wafers may be used to run marathons, test equipment and for high-end R & D. They are often a cost-effective alternative to prime wafers.

For weakly doped n-InP at temperatures close to 300 K electron drift mobility:

µn = (4.2÷5.4)·103·(300/T) (cm2V-1 s-1)

Approximate formula for electron Hall mobility

µ=µOH/[1+(Nd/107)1/2],
where µOH=5000 cm2V-1 s-1,
Nd- in cm-3 (Hilsum [1974])

At 300 K, the electron Hall factor rn≈1 in n-InP.
for Nd > 1015 cm-3.

For weakly doped p-InP at temperature close to 300 K the Hall mobility

µpH~150·(300/T)2.2 (cm2V-1 s-1).

At 300 K, the hole factor in pure p-InP: rp~1

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.
