Impact of carrier localization on recombination in InGaN quantum wells and the efficiency of nitride light-emitting diodes: insights from theory and numerical simulations
Christina Jones, Chu-Hsiang Teng, Qimin Yan +2
We examine the effect of carrier localization due to random alloy fluctuations on the radiative and Auger recombination rates in InGaN quantum wells as a function of alloy composit…
Site-controlled InGaN/GaN single-photon-emitting diode
Lei Zhang, Chu-Hsiang Teng, Pei-Cheng Ku +1
We report single-photon emission from electrically driven site-controlled InGaN/GaN quantum dots, fabricated from a planar light-emitting diode structure containing a single InGaN…
Charge-Tunable Indium Gallium Nitride Quantum Dots
Lei Zhang, Chu-Hsiang Teng, Pei-Cheng Ku +1
III-Nitride quantum dots have emerged as a new chip-scale system for quantum information science, which combines electrical and optical interfaces on a semiconductor chip that is c…
How much better are InGaN/GaN nanodisks than quantum wells - oscillator strength enhancement and changes in optical properties
Lei Zhang, Leung-Kway Lee, Chu-Hsiang Teng +3
We show over 100-fold enhancement of the exciton oscillator strength as the diameter of an InGaN nanodisk in a GaN nanopillar is reduced from a few micrometers to less than 40 nm,…
Carrier dynamics in site- and structure-controlled InGaN/GaN quantum dots
Lei Zhang, Tyler A. Hill, Chu-Hsiang Teng +3
We report on the carrier dynamics in InGaN/GaN disk-in-a-wire quantum dots with precisely controlled location and structural parameters, including diameter, thickness and material…
Inducing electron spin coherence in GaAs quantum well waveguides: Spin coherence without spin precession
Susanta Sarkar, Phedon Palinginis, Hailin Wang +4
Electron spin coherence is induced via light-hole transitions in a quantum well waveguide without either an external or internal DC magnetic field. In the absence of spin precessio…
