Unraveling Intrinsic Thermal Conductivity in Layered Conductive MOF Single Crystals
Jinkun Guo, Dongyang Wang, Zhiyi Li +8
Layered conductive metal-organic frameworks (LCMOFs) show great promise in energy and electronics due to their high electrical conductivity and tunable pore structures. They are co…
Significant reduction in semiconductor interface resistance via interfacial atomic mixing
Qichen Song, Jiawei Zhou, Gang Chen
The contact resistance between two dissimilar semiconductors is determined by the carrier transmission through their interface. Despite the ubiquitous presence of interfaces, quant…
Simultaneously high electron and hole mobilities in cubic boron-V compounds: BP, BAs and BSb
Te-Huan Liu, Bai Song, Laureen Meroueh +5
Through first-principles calculations, the phonon-limited transport properties of cubic boron-V compounds (BP, BAs and BSb) are studied. We find that the high optical phonon freque…
