题目 Convergence of multi-valley bands as the electronic origin of high thermoelectric performance in CoSb3 skutterudites 作者 Yinglu Tang,Zachary M. Gibbs,Luis A. Agapito, Guodong Li,Hyun-Sik Kim, Marco Buongiorno Nardelli,Stefano Curtarolo & G. Jeffrey Snyder 摘要 Filled skutterudites RxCo4Sb12 are excellent n-type thermoelectric materials owing to their high electronic mobility and high effective mass, combined with low thermal conductivity associated with the addition of filler atoms into the void site. The favourable electronic band structure in n-type CoSb3 is typically attributed to threefold degeneracy at the conduction band minimum accompanied by linear band behaviour at higher carrier concentrations, which is thought to be related to the increase in effective mass as the doping level increases. Using combined experimental and computational studies, we show instead that a secondary conduction band with 12 conducting carrier pockets (which converges with the primary band at high temperatures) is responsible for the extraordinary thermoelectric performance of n-type CoSb3 skutterudites. A theoretical explanation is also provided as to why the linear (or Kane-type) band feature is not beneficial for thermoelectrics. |

大佬帮着分析今年的评审意见？该课题连续申请了三年了，明年要不要换个方向。
