Gate-Tunable Multi-Band van der Waals Photodetector and Polarization Sensor
Daozhi Shen, HeeBong Yang, Tarun Patel +5
A single photodetector with tunable detection wavelengths and polarization sensitivity can potentially be harnessed for diverse optical applications ranging from imaging and sensin…
High-Performance Mid-IR to Deep-UV van der Waals Photodetectors Capable of Local Spectroscopy at Room Temperature
Daozhi Shen, HeeBong Yang, Christian Spudat +13
The ability to perform broadband optical spectroscopy with sub-diffraction-limit resolution is highly sought-after for a wide range of critical applications. However, sophisticated…
Infrared imaging of samples in ultra high pressure diamond anvil cells
Tarun Patel, A. Drozdov, V. S. Minkov +5
We describe an experimental platform that generates infrared images of micrometer-sized samples in the high pressure region of a diamond anvil cell. Using a 2.3 micron laser as a s…
Optical properties of superconducting pressurized LaH
Sabri Elatresh, T. Timusk, E. J. Nicol
Recently superconductivity has been discovered at around 200~K in a hydrogen sulfide system and around 260~K in a lanthanum hydride system, both under pressures of about 200 GPa. T…
Spectroscopic signatures of phonons in high pressure superconducting hydrides
J. P. Carbotte, E. J. Nicol, T. Timusk
The discovery of superconductivity at 203K in SH is an important step toward higher values of . Predictions based on state-of-the-art DFT for the electronic structure, inc…
Optical Signatures of Dirac Nodal-lines in NbAs
Yinming Shao, Zhiyuan Sun, Ying Wang +10
Using polarized optical and magneto-optical spectroscopy, we have demonstrated universal aspects of electrodynamics associated with Dirac nodal-lines. We investigated anisotropic e…
