Band structure and optical transitions of mixed crystals Hg1−x Cd x Te

Зонная структура и оптические переходы в смешанных кристаллах Hg1−x Cd x Te

Summary

We perform calculations of the band structure of Hg1−x Cd x Te using distorted atomic orbitals as localized basis functions. The role of all relativistic corrections in the inversion of bands is discussed. Nonlinear concentration dependence of the energy gaps atL is found in fair agreement with the experimental results.

Riassunto

Si presenta un calcolo della struttura a bande dei cristalli Hg1−x Cd x Te, in cui si usano come funzioni di base localizzate orbitali atomici distorti. Si discute il ruolo di tutte le correzioni relativistiche nell’inversione delle bande. Si trova che le gap energetiche al puntoL dipendono dalla concentrazione in modo non lineare, approssimativamente in accordo con i dati sperimentali.

Резюме

Проводится вычисление зонной структуры Hg1−x Cd x Te, используя искаженные атомные орбитали, как локализованные базисные функции. Обсуждается роль всех релятивистских поправок при инверсии зон. Обнаружено, что нелинейная зависимость от концентрации для энергетических щелей вL удовлетворительно согласуется с экспериментальными результатами.
