Ultralow Electron-Surface Scattering in Nanoscale Metals Leveraging Fermi Surface Anisotropy
Sushant Kumar, Christian Multunas, Benjamin Defay +2
Increasing resistivity of metal wires with reducing nanoscale dimensions is a major performance bottleneck of semiconductor computing technologies. We show that metals with suitabl…
Fermi surface anisotropy in plasmonic metals increases the potential for efficient hot carrier extraction
Sushant Kumar, Christian Multunas, Ravishankar Sundararaman
Realizing the potential of plasmonic hot carrier harvesting for energy conversion and photodetection requires new materials that resolve the bottleneck of extracting carriers prior…
Circular Dichroism of Crystals from First Principles
Christian Multunas, Andrew Grieder, Junqing Xu +2
Chiral crystals show promise for spintronic technologies on account of their high spin selectivity, which has led to significant recent interest in quantitative characterization an…
Spin Dynamics in Hybrid Halide Perovskites -- Effect of Dynamical and Permanent Symmetry Breaking
Kejun Li, Junqing Xu, Uyen N. Huynh +7
The hybrid organic-inorganic halide perovskite (HOIP), for example MAPbBr3, exhibits extended spin lifetime and apparent spin lifetime anisotropy in experiments. The underlying mec…
