It is direct band gap material.

Yes it is. Most Sn (tin) materials as semiconductors are direct band gap materials. Silicon on the other hand is an indirect band gap material.
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.
Amorphous Silicon (a-Si) has band gap of about 1.7eV, whereas crystalline (c-Si) only has a band gap of 1.1eV
Gallium Arsenide (GaAs) has a 2.5eV band gap (@ 295 K)
at 300 Kelvin, silicon band gap is 1.11 eV, Germaium band gap is 0.66 eV.source: hyperphysics.phy-astr.gsu.edu/hbase/Tables/Semgap.html
The difference in energy levels between the valence band and the conduction band is called the "band gap" or "energy gap." This band gap determines the electrical conductivity of a material; in insulators, it is large, while in conductors, it is small or nonexistent. In semiconductors, the band gap is moderate, allowing for controlled conductivity under certain conditions, such as temperature changes or doping.
