Lasers that are fabricated directly onto silicon photonic chips offer several advantages over external laser sources, such as ...

We use density functional theory including Heyd Scuseria Ernzerhof (HSE) hybrid functionals to investigate the electronic structure of Ge1-xSnx and Ge1-yCy supercells. The calculations confirm that a ...

This study aimed to calculate the band gap energy of a germanium semiconductor diode using computational tools. The energy gap calculation was conducted by immersing the semiconductor diode in an oil ...
