摘要:通过第一性原理计算研究电场强度和方向对于g-C3N4/germanene双层的结合能、态密度以及电荷的影响.计算结果显示,电场对于双层的物理性质影响很大,方向朝上的电场使得态密度曲线向左移动,同时方向朝下的电场使得态密度曲线朝右移动.并且在电场的影响下,功函数的变化不大.
Effect of electric field intensity and direction on binding energy,density of states(DOS),and charge density of g-C3N4/germanene heterobilayer was investigated by first principle calculations.The calculation results reveal the large impact of electric field on the physical parameters of g-C3N4/germanene heterobilayer.Application of upward electric field moves the DOS towards left,while the downward electric field results in the right-shift of DOS in g-C3N4/germanene heterobilayer.In addition,no changes in work function of heterobilayer occur under electric fields.
