概要
- 論文の詳細を見る
The time-dependent 2-dimensional Schrödinger equation wassolved with the finite element method to investigate the electron tunneling phenomena in a planar-type quantum disk with the electrodessystem. Tunneling time, which was determined at the electron probability amplitude to reach a steady state, is longerthrough a thin potential barrier than that through a thick barrier.Mode formation process is analyzed with energy spectra in the quantum dot. An ionized impurity introduced in the quantumdot is shown to have a significant effect on the sequentialtunneling transfer through the dot.
