Intersubband optical absorption in parabolic quantum wires under a tilted magnetic field

Abstract

PACS 78.20 Ci, 78.20Ls, 78.67.Lt We have analyzed the intersubband absorption process in parabolic quantum wires in the presence of a tilted magnetic field. We show that for an increasing magnetic field, the intersubband absorption peak is shifted higher in energy and the peak amplitude is increased. In particular, it is shown that the direction of the magnetic field plays a significant role in the intersubband optical absorption.

“…Более того, эти степенные законы отличаются от классической зависимости k 2 коэффициента поглощения. Поглощение света свободными носителями при рассеянии электронов на фононах теоретически исследовалось в полупроводниковых квантовых ямах и проволоках [18][19][20][21][22][23][24][25][26][27][28] и в квантовых точках [29,30].…”

“…The investigation of intraband absorption in QWW [8,9] is very important as well. Today, the effects related to transitions of charge carriers from the localized levels to continuum states are intensively investigated, because of their use in new type IR receivers [10,11].…”
