Nonlinear optical rectification in asymmetrical semiparabolic quantum wells

, 2005
The optical rectification in a semiparabolic quantum well is theoretically investigated. The electronic states in a semiparabolic quantum well are calculated exactly, within the envelope function and the displaced harmonic oscillator approach.

Interfacial Electronic Restructuring in MAPbBr3/rGO Hybrids Enabling Improved Charge Extraction for Efficient Photodetection

Advanced Materials Interfaces, EarlyView.
MAPbBr3/rGO hybrids exhibit interfacial electronic restructuring that enhances charge extraction in photodetectors. The incorporation of rGO modifies the surface chemical environment, enhances electron‐dominated transport, and suppresses performance degradation, resulting in higher responsivity, detectivity, and photostability than in pristine MAPbBr3 ...

Rectifying and Photoconductive Responses in Graphene–Double-Insulator–Graphene (GI²G) Structures

C
Advanced solar energy-harvesting devices, such as optical rectennas, typically use metal–insulator–metal diodes because of the ultrafast response of these diodes at high frequencies. However, the diode performance is limited by weak current–voltage (I–V)

Surface‐Plasmon‐Coupled Blue InGaN/GaN Micro‐LEDs with Oxide–Metal–Oxide Capping Layer Compatible to Chip Fabrication Process

Advanced Optical Materials, EarlyView.
A sidewall‐integrated oxide–metal–oxide architecture is demonstrated to overcome efficiency degradation in ultra‐small InGaN/GaN micro‐LEDs. Conformal Al2O3 passivation combined with plasmonic Ag nanoparticles enables localized surface plasmon–exciton coupling, converting surface‐related nonradiative losses into radiative emission.
