웹Examples of indirect band gap semiconductor materials are silicon (Si), germanium (Ge), aluminum arsenide (AlAs) and gallium phosphide (GaP). Because of the reduced absorption coefficients, silicon layers in … 웹Unfortunately bulk germanium is an indirect band gap semiconductor. Here, we demonstrate that a thick germanium layer can be transformed from an indirect into a direct band gap semiconductor by using silicon nitride stressor layers. We achieve 1.75% (1.67%) biaxial tensile strain in 6 (9) μm diameter microdisks as measured from photoluminescence.

The indirect energy gap, E g (L) = 664 meV at 300 K, is between the highest valence band (VB) state at Γ and the lowest ...
웹However, we find also that the band gap energy varies with temperature, even in the literature, instead of being a constant as we have earlier supposed. In particular, at 0 K, the band gap of germanium is 0.74 eV, which is quite close to our measured values. Phenomenologically, this temperature dependence can be modelled as ∆E (T ) = ∆E (0 ...
