关注: 1) 怎样理解 the DOS for equivaalent free-electron systems. 2) 怎样清楚明了的问答问题。 答: 答: Dear Xiao-qiu, The formulas you have there are correct, but you also need the equation for the general density of states of the free 3D electron gas. That is fo ...
关注: 1) 什么是 DOS for equivalent free-electron systems. 2) 什么样的金属是好的导体,什么样的是不好的导体,如何从费米能级附近的态密度看出来? Density of states The density of states (DOS) corresponds to electrons with a spherically-symmetric parabolic dispersion , with two electron ...
关注: 1) 什么情形下要考虑非谐效应 This analysis predicts veryinteresting implications upon isotopic substitution in the dihydrogen unit. Thevibrational energy levels are lowered when heavier isotopes are introduced. Asa consequence, and again due to theanharmonicity, ...
