MIT’s Plasma Science and Fusion Center (PSFC) will substantially expand its fusion energy research and education activities under a new five-year agreement with Institute spinout Commonwealth Fusion S...
利用密度泛函理论和非平衡态格林函数相结合的方法，系统地研究了边修饰Net-Y纳米带的电子结构和器件特性的应变调控效应。计算表明：本征纳米带为金属，但边缘的氢或氧原子端接能使其转变为半导体。应变能有效地调控纳米带带隙的大小，适当的应变使能带结构从间接带隙转变为较小的直接带隙，这有利于光的吸收。应变也能改变纳米带的功函数，压缩应变能明显减小功函数，这有利于纳米带实现场发射功能。特别是应变能有效地调控纳...
近日，中国科学院物理研究所/北京凝聚态物理国家研究中心研究员王建涛、博士聂思敏、研究员翁红明，日本东北大学教授川添良幸，美国内华达大学教授陈长风合作，通过第一性原理计算，提出一个新的三维碳烯晶体结构【图1(a)】。该结构具有体心正方对称性(I4/mmm)，单位晶胞包含40个碳原子，因此简称为BCT-C40。它可以看做是一维(5,5)碳纳米管的三维重构形式，但能量上比(5,5)碳纳米管、fcc-C6...
Probing the QCD Critical Point with Higher Moments of Net-proton Multiplicity Distributions
Net-proton Multiplicity Distributions QCD Critical Point
2011/7/21
Higher moments of event-by-event net-proton multiplicity distributions are applied to search for the QCD critical point in the heavy ion collisions. It has been demonstrated that higher moments as wel...
