Revealing unusual bandgap shifts with temperature and bandgap renormalization effect in phase-stabilized metal halide perovskite thin films
Haochen Zhang, Zhixuan Bi, Zehua Zhai +11
Hybrid organic-inorganic metal halide perovskites are emerging materials in photovoltaics, whose bandgap is one of the most crucial parameters governing their light harvesting perf…
Antiferromagnetic Topological Insulator MnBi2Te4: Synthesis and Magnetic properties
Hao Li, Shengsheng Liu, Chang Liu +6
Recently, MnBi2Te4 has been discovered as the first intrinsic antiferromagnetic topological insulator (AFM TI), and will become a promising material to discover exotic topological…
Temperature-Dependent Electron-Electron Interaction in Graphene on SrTiO3
Hyejin Ryu, Jinwoong Hwang, Debin Wang +6
The electron band structure of graphene on SrTiO3 substrate has been investigated as a function of temperature. The high-resolution angle-resolved photoemission study reveals that…
Variability Effects in Graphene: Challenges and Opportunities for Device Engineering and Applications
Guangyu Xu, Yuegang Zhang, Xiangfeng Duan +2
Variability effects in graphene can result from the surrounding environment and the graphene material itself, which form a critical issue in examining the feasibility of graphene d…
Fermi velocity engineering in graphene by substrate modification
Choongyu Hwang, David A. Siegel, Sung-Kwan Mo +5
The Fermi velocity is one of the key concepts in the study of a material, as it bears information on a variety of fundamental properties. Upon increasing demand on the device appli…
Edge effect on resistance scaling rules in graphene nanostructures
Guangyu Xu, Carlos M. Torres, Jianshi Tang +6
We report an experimental investigation of the edge effect on the room-temperature transport in graphene nanoribbon and graphene sheet (both single-layer and bilayer). By measuring…
