  1. Since the concept of superlattice was proposed, vertical transport in superlattice has been investigated widely. the electric field domains and current self - oscillations which result from sequential resonant tunneling between different subbands of the superlattice are very significant phenomena. such kind of oscillation can be uesd to make tunable microwave oscillaors. in this thesis, low temperature transport problem, especially the formation of field domain and the condition of current self - oscillations in doped gaas / alas superlattice with weak coupling are investigated thoroughly and also by combining the macroscopic model with the microscopic one., the voltage - current characteristic and the current oscillation are simulated. the calculated result is nearly consistent with the experimental data

    超晶格中子能級之間的順序多阱共振隧穿引起的電場疇及電維持振蕩現象是其中的一個非常有意義的分支,該現象可用來製作電壓調諧微波振蕩器。本論文對弱耦合摻雜gaaa alas超晶格中的縱向輸運特別是針對低溫下的場疇的形成和固定偏壓下電維持振蕩產生的條件進行了深入的探討,並結合宏觀和微觀對超晶格在時變電壓作用下的電壓-電特性以及固定偏壓作用下的電特性進行了擬計算。
