in indirect band gap semiconductors ,the effective mass isn't constant , because of the anisotropie of this effective mass there are (longitidinal and transversal effective mass). for calculate the optical parameters in semiconductor , i need electron and hole effective masses , what the value of electron effective mass in this type of semiconductors ( transversal or longitidinal ?)(adsbygoogle = window.adsbygoogle || []).push({});

thank you
