Gallium Arsenide (GaAs) has a 2.5eV band gap (@ 295 K)
The Gap Band III was created in 1980.
No GaAs is a semiconductor- and as such is essentially a covalent compound.
The Gap Band consists of brothers Charlie, Robert and Ronnie Wilson, the band first formed as the Greenwood, Archer and Pine Street Band in 1967. The group later changed their name to The Gap Band. Look up "You dropped a bomb on me" by The Gap Band.

The gap band
Yes it is.
I think because GaAs has a direct band gap transition but Si and Ge has indirect band gap transition. Both silicon and germanium are opaque and thus cannot be used to make LASERs.

Direct band gap semiconductors are used in light-emitting diodes (LEDs) because they allow for efficient photon emission when electrons recombine with holes. In these materials, the transition from the conduction band to the valence band occurs at the same momentum, enabling the direct release of energy in the form of light. This efficiency in light production is crucial for applications in displays and lighting. Examples of direct band gap semiconductors include gallium arsenide (GaAs) and indium gallium nitride (InGaN).
the stewpid kined
see wavelength=1.24/Band gap energy this wavelength is in micrometer.so accordingly ans will be=1.24/1.42=0.873micrometer I think u had appeared in BSNL JTO. How many u attempted?? Vijay
The Gap Band was created in 1967.
Gaas's population is 450.
direct band gap-semiconductor in which the bottom of the conduction band and the top of the valence band occur at the momentum k=0;in the case of d.b.s. energy released during band-to-band electron recombination with a hole is converted primarily into radiation (radiant recombination); wavelength of emitted radiation is determined by the energy gap of semiconductor; examples of d.b.s. GaAs, InP, ZnS, ZnSs, CdS, CdSe etc. indirect bandgap semiconductor --semiconductor in which bottom of the conduction band does not occur at effective momentum k=0, i.e. is shifted with respect to the top of the valence band which occurs at k=0; energy released during electron recombination with a hole is converted primarily into phonon; e.g. Si, Ge, GaP, GaAsp ,Ge etc, .

It is direct band gap material.
The Gap Band II was created in 1979.
