Direct Visualization of Electric Field induced Structural Dynamics in Monolayer Transition Metal Dichalcogenides
Akshay A. Murthy, Teodor K. Stanev, Roberto dos Reis +4
Layered transition metal dichalcogenides (TMDs) offer many attractive features for next-generation low-dimensional device geometries. Due to the practical and fabrication challenge…
Leveraging Electron-Phonon Interaction to Enhance Thermoelectric Power Factor in Graphene-Like Semimetals
Yi Xia, Junsoo Park, Vidvuds Ozoliņš +1
Electron-phonon interaction (EPI) is presumably detrimental for thermoelectric performance in semiconductors because it limits carrier mobility. Here we show that enhanced EPI with…
Electronic Structure and Phase Stability of Yb-filled CoSb Skutterudite Thermoelectrics from First Principles
Eric B. Isaacs, Chris Wolverton
Filling the large voids in the crystal structure of the skutterudite CoSb with rattler atoms provides an avenue for both increasing carrier concentration and disrupting lat…
An Enormous Class of Double Half-Heusler Compounds with Low Thermal Conductivity
Shashwat Anand, Max Wood, Chris Wolverton +1
Since their discovery around a century ago, the structure and chemistry of the multi-functional half-Heusler semiconductors have been studied extensively as three component systems…
