Stable electroluminescence in ambipolar dopant-free lateral p-n junctions
Lin Tian, Francois Sfigakis, Arjun Shetty +11
Dopant-free lateral p-n junctions in the GaAs/AlGaAs material system have attracted interest due to their potential use in quantum optoelectronics (e.g., optical quantum computers…
Quantum Interference Enhances the Performance of Single-Molecule Transistors
Zhixin Chen, Iain M. Grace, Steffen L. Woltering +9
An unresolved challenge facing electronics at a few-nm scale is that resistive channels start leaking due to quantum tunneling. This affects the performance of nanoscale transistor…
Field effect two-dimensional electron gases in modulation-doped InSb surface quantum wells
E. Annelise Bergeron, F. Sfigakis, Y. Shi +6
We report on transport characteristics of field effect two-dimensional electron gases (2DEG) in surface indium antimonide quantum wells. The topmost 5 nm of the 30 nm wide quantum…
Phase-Coherent Charge Transport through a Porphyrin Nanoribbon
Zhixin Chen, Jie-Ren Deng, Songjun Hou +9
Quantum interference in nano-electronic devices could lead to reduced-energy computing and efficient thermoelectric energy harvesting. When devices are shrunk down to the molecular…
Charge-state dependent vibrational relaxation in a single-molecule junction
Xinya Bian, Zhixin Chen, Jakub K. Sowa +8
The interplay between nuclear and electronic degrees of freedom strongly influences molecular charge transport. Herein, we report on transport through a porphyrin dimer molecule, w…
Observation and manipulation of a phase separated state in a charge density wave material
Sean M. Walker, Tarun Patel, Junichi Okamoto +8
The 1T polytype of TaS has been studied extensively as a strongly correlated system. As 1T-TaS is thinned towards the 2D limit, its phase diagram shows si…
