초록
우리는 준 2차원 Landau 분할 시스템의 양자 광학 전이 특성을 실리콘(Si)에서 이론적으로 고찰하였다. Squre wall 구속포텐셜에 의한 전자 구속 시스템에 양자 수송 이론(QTR)을 적용하였습니다. 평형 평균 투영 계획(Equilibrium AverageProjection Scheme：EAPS)으로 계획된 Liouville 방정식 방법을 사용하였으며, 양자 전이를 분석하기 위해 포톤 방출 전이과정과 포논 흡수 전이 과정의 두 전이 과정에서 QTLW와 QTLS의 온도와 자기장 의존성을 비교하였습니다. 이 연구를 통해 Si의 QTLW와 QTLS의 온도와 자기장의 증가하는 특성을 발견하였으며, 또한 우세한 산란 과정이 포논 방출 전이 과정이라는 것을 발견했다.
Abstract
We investigated theoretically the quantum optical transition properties of qusi 2-Dinensinal Landau splitting system, inSi. We apply the Quantum Transport theory (QTR) to the system in the confinement of electrons by square wellconfinement potential. We use the projected Liouville equation method with Equilibrium Average Projection Scheme(EAPS). In order to analyze the quantum transition, we compare the temperature and the magnetic field dependencies ofthe QTLW and the QTLS on two transition processes, namely, the phonon emission transition process and the phononabsorption transition process. Through the analysis of this work, we found the increasing properties of QTLW and QTLSof Si with the temperature and the magnetic fields. We also found the dominant scattering processes are the phononemission transition process.
