Summary:	在本論文中，我們探討單一電子侷限在量子環中的電子性質，藉由外加磁場或電場來影響其物理特性，並利用矩陣方法求解系統的能階與波函數。當量子環通有一磁場時，會使能階產生週期性的震盪行為，一旦系統摻有雜質，則雜質的數量與間距角度會影響能階的簡併現象。此外，當一個通有電場的量子環上施加位勢壘時，電子在位勢壘阻礙的影響下，使能階產生明顯的反交叉與偏移現象，最後我們進一步探討不同系統條件對熱容量性質的影響。 In this thesis, we investigate the electronic properties of quantum rings in magnetic and electric fields. We use the matrix method to obtain the energy spectrum and wave function. Numerical results demonstrate that the magnetic and electric fields strongly affect the physical characteristics of quantum rings. When a magnetic field is applied to the ring, the energy levels show periodic oscillations. We further consider the system including several impurities. The parameters of impurities have a great influence on the degeneracies of energy levels. On the other hand, the electric field and hindering barriers lead to anticrossing behaviors in the energy levels. Finally, we study the heat capacity of quantum-ring systems in the external fields.
