【摘要】 应用准经典粒子理论和量子力学测不准关系,得到了在三角形势阱中二维电子气的能级宽度,基于这个计算结果,发现三角形势阱中的二维电子气的基态第一激发态的能级宽度比导带的能级宽度要大,同时,随着电场强度的增大,相应的能级宽度也要增宽。更多还原

【Abstract】 According to theories of quasi-classical particles and the uncertainty relation of quantum mechanics, we deduce the formula of energy uncertainty with electric field. We use it to two dimension electron gas (2DEG) in triangular well and get its energy width.Based on these, we find that energy width will increase along with the increasing of electronic field intensity.At the same time, the energy width of the first excitated state is wider than the ground state.更多还原
