The drift velocity is the average Velocity that a particle such as an Electron, attains due to an Electric field. Silicon (ˈsɪlɪkən or /ˈsɪlɪkɒn/ silicium is the Chemical element that has the symbol Si and Atomic number 14 Gallium arsenide ( GaAs) is a compound of two elements Gallium and Arsenic. It also has a direct bandgap, making it useful for optoelectronics devices like laser diodes. In Semiconductor Physics, a direct Bandgap means that the minimum energy of the Conduction band lies directly above the maximum energy of the Optoelectronics is the study and application of electronic devices that source detect and control Light, usually considered a sub-field of Photonics. A laser diode is a Laser where the active medium is a Semiconductor similar to that found in a Light-emitting diode.

InP is also used as a substrate for epitaxial indium gallium arsenide based opto-electronic devices. Epitaxy refers to the method of depositing a Monocrystalline film on a monocrystalline substrate Indium gallium arsenide ( InGaAs) is a Semiconductor composed of Indium, Gallium and Arsenic.

Indium phosphide also has one of the longest-lived optical phonons of any compound with the zincblende crystal structure. In Physics, a phonon is a quantized mode of vibration occurring in a rigid crystal lattice, such as the Atomic lattice of a Solid Sphalerite (( Zn, Fe) S) is a Mineral that is the chief Ore of Zinc. In Mineralogy and Crystallography, a crystal structure is a unique arrangement of Atoms in a Crystal.

## Optical properties

The Sellmeier equation that describes how the optical refractive index for indium phosphide depends on wavelength is given by $n^2(\lambda) = 7.255+ \frac{2.316 \lambda^2 }{ \lambda^2 - 0.6263^2}+ \frac{2.765 \lambda^2 }{ \lambda^2 - 32.935^2},$ where λ is the wavelength in micrometres. In Optics, the Sellmeier equation is an Empirical relationship between Refractive index n and Wavelength λ for a The refractive index (or index of Refraction) of a medium is a measure for how much the speed of light (or other waves such as sound waves is reduced inside the medium In Physics wavelength is the distance between repeating units of a propagating Wave of a given Frequency. A micrometre ( American spelling: micrometer; symbol µm) is one millionth of a Metre, or equivalently one thousandth of a Millimetre

This gives refractive index values rising from around 3. 21 at 10 µm and 3. 32 at 1. 5 µm to 3. 47 at 1. 0 µm.
