Both views have sound scientific arguments in favour of them. Since the nuclear field, both in industry and medicine, has had to deal with this controversy for many decades, one can argue that the optimisation approach to keep the effective doses as low as reasonably achievable, taking ...
在这里, 我们首先采用PBE的密度函数计算了锑体材料的电子能带结构, 如图2所示, 结果表明锑体材料的带隙为零, 它的价带和导带交于零能量处, 形成了一个狄拉克锥, 这个交点称为狄拉克点, 说明其具有半金属材料特性, 该计算结果和实际是相符合的. 而对于少层(1–4层)锑烯的电子能带结构, 则如图3(a)所示....
