Gap direct.

Direct bandgap semiconductors A common and simple method for determining whether a band gap is direct or indirect uses absorption spectroscopy . By plotting certain powers of the absorption coefficient against photon energy, one can normally tell both what value the band gap has, and whether or not it is direct. α2

Gallium phosphide ( GaP ), a phosphide of gallium, is a compound semiconductor material with an indirect band gap of 2.24 eV at room temperature. Impure polycrystalline material has the appearance of pale orange or grayish pieces. Undoped single crystals are orange, but strongly doped wafers appear darker due to free-carrier absorption.With temperature energy band gap decreases. With increasing temperature, carriers get extra energy to over come the gap. Thus, effective bandgap is reduced. This leads to increased leakage current ...

direct in ZB structure such as for GaN and ZnO, it is also direct in WZ structure; if the band gap is indirect in ZB structure such as for AlN, it could still be direct in WZ structure due to the average of the X and L point wavefunctions. The relative energy positions between the Γ-valley, X-valley, and L-valley in the lowest conduction band ...However, even if an indirect-gap device is just as efficient as a direct-gap device, you will still need to use 100 to 1000 times as much absorber material to make a functioning device.
