The total energy of an
element is the basic energy value from which other properties of the element
can be calculated. Aluminum Arsenide (AlAs) and Indium Arsenide (InAs) are III
– Arsenic binary semiconductors with indirect and direct energy band gap
respectively. The total energy of each of them was calculated using the
Projector Augmented Wave (PAW) method with the PBE-GGA for the
exchange-correlation functional. The total energy were calculated and from the
results gotten, the la...
