GeAlS
GeAlS, or Gallium Aluminum Selenide, is a ternary compound semiconductor composed of gallium (Ga), aluminum (Al), and selenium (Se). It belongs to the broader class of III-VI semiconductors, which combine elements from group III (gallium and aluminum) and group VI (selenium) of the periodic table. The material is notable for its tunable bandgap properties, making it useful in optoelectronic applications.
The crystal structure of GeAlS typically follows the zincblende or wurtzite lattice, depending on synthesis conditions.
GeAlS is synthesized through techniques such as molecular beam epitaxy (MBE) or metalorganic vapor phase epitaxy
Compared to traditional semiconductors like silicon or gallium arsenide, GeAlS offers advantages in specific wavelength ranges,
