    • A solution for designing and/or fabricating a structure including a quantum well and an adjacent barrier is provided. A target band discontinuity between the quantum well and the adjacent barrier is selected to coincide with an activation energy of a dopant for the quantum well and/or barrier. For example, a target valence band discontinuity can be selected such that a dopant energy level of a dopant in the adjacent barrier coincides with a valence energy band edge for the quantum well and/or a ground state energy for free carriers in a valence energy band for the quantum well. Additionally, a target doping level for the quantum well and/or adjacent barrier can be selected to facilitate a real space transfer of holes across the barrier. The quantum well and the adjacent barrier can be formed such that the actual band discontinuity and/or actual doping level(s) correspond to the relevant target(s).
    • 提供了一种用于设计和/或制造包括量子阱和相邻屏障的结构的解决方案。 选择量子阱和相邻屏障之间的目标频带不连续性以与量子阱和/或屏障的掺杂剂的活化能一致。 例如,可以选择目标价带不连续性,使得相邻势垒中的掺杂剂的掺杂剂能级与量子阱的价态能带边缘和/或价态能带中的自由载流子的基态能量一致 量子阱。 另外,可以选择量子阱和/或相邻势垒的目标掺杂水平以促进穿过势垒的空穴的实际空间传递。 可以形成量子阱和相邻势垒,使得实际的带不连续性和/或实际掺杂水平对应于相关目标。
