Bu tezde silisyum, germanyum ve ikili yarıiletken bileşiklerin taban durumunda örgü sabiti, bant aralığı , hacim modülü farklı pseudopotansiyeller kullanılarak hesaplanmış ve çıkan sonuçlar la karşılaştırılmıştır. L iteratür değerlerine en yakın sonucu veren pseudopotansiyel seçilerek bant yapısı ve durum yoğunluğu hem silisyum ve germanyum için hem d e ikili yarıiletken bileşikler , InAs, GaAs , GaP ) için çizilmiştir. Hesaplamalar Quantum Espresso adlı bir modelleme programında Düzlem Dalga Öz Uyumlu Alan bileşeni kullanılarak yapılmıştır. Program sonucundan elde edilen değerler lite ratür değerleriyle karşılaştırılmıştır. Seçilen parametrele rin hesaplanan sonuçlar üzerinde etkisi olduğu görülmüştür.In this thes is, the lattice...
