$Psi=0$ at a sharp semiconductor/insulator interface. Is this correct? | L. Braginsky

29 Sep 1999 | Subject: | Mesoscopic Systems and Quantum Hall Effect; Materials Science | cond-mat.mes-hall cond-mat.mtrl-sci | Abstract: | The generalized boundary conditions for the envelope wave function that take into account the real structure of an interface were used to investigate the hole spectrum of the semiconductor quantum dot embedded in an insulator matrix. An essential influence of the interface levels, which could exist at the top of the valence band, on the hole spectrum has been demonstrated. It is found that usually applied boundary conditions, wherein all components of the envelope wave function vanish at the interface, can be used only in the absence of the interface levels close to the band edge. | Source: | arXiv, cond-mat/9909408 | Services: | Forum | Review | PDF | Favorites |
