Direct Observation of Gate Tunable Dark Trions in Monolayer WSe2
Zhipeng Li, Tianmeng Wang, Zhengguang Lu +11
Spin-forbidden intravalley dark exciton in tungsten-based transition metal dichalcogenides (TMDCs), owing to its unique spin texture and long lifetime, has attracted intense resear…
Phase Modulators Based on High Mobility Ambipolar ReSe2 Field-Effect Transistors
Nihar R. Pradhan, Carlos Garcia, Bridget Isenberg +11
We fabricated ambipolar field-effect transistors (FETs) from multi-layered triclinic ReSe2, mechanically exfoliated onto a SiO2 layer grown on p-doped Si. In contrast to previous r…
Photoconductivity of few-layered p-WSe2 phototransistors via multi-terminal measurements
Nihar R. Pradhan, Carlos Garcia, Joshua Holleman +6
Recently, two-dimensional materials and in particular transition metal dichalcogenides (TMDs) were extensively studied because of their strong light-matter interaction and the rema…
High Photoresponsivity and Short Photo Response Times in Few-Layered WSe Transistors
Nihar R. Pradhan, Jonathan Ludwig, Zhengguang Lu +6
Here, we report the photoconducting response of field-effect transistors based on three atomic layers of chemical vapor transport grown WSe crystals mechanically exfoliated ont…
Fermi-Edge Superfluorescence from a Quantum-Degenerate Electron-Hole Gas
J. -H. Kim, G. T. Noe, S. A. McGill +4
We report on the observation of spontaneous bursts of coherent radiation from a quantum-degenerate gas of nonequilibrium electron-hole pairs in semiconductor quantum wells. Unlike…
High-Performance, Hysteresis-Free Carbon Nanotube FETs via Directed Assembly
S. A. McGill, S. G. Rao, P. Manandhar +2
High-performance single-wall carbon nanotube field-effect transistors (SWNT-FETs) are fabricated using directed assembly and mass-produced carbon nanotubes (CNTs). These FETs exhib…
