EFFICIENCY DROOP SUPPRESSION OF DISTANCE-ENGINEERED SURFACE PLASMON-COUPLED PHOTOLUMINESCENCE IN GAN-BASED QUANTUM WELL LEDS

Efficiency droop suppression of distance-engineered surface plasmon-coupled photoluminescence in GaN-based quantum well LEDs

Ag coated Hall Trees microgroove with extreme large aspect-ratio of 500:1 was fabricated on p-GaN capping layer to investigate the coupling behavior between quantum wells and surface plasmon in highly spatial resolution.Significant photoluminescence enhancement was observed when the distance between Ag film and QWs was reduced from 220 nm to about

Dynamical stability analysis of accelerating f(T) gravity models

Abstract In this paper, we have emphasized the stability analysis of the accelerating cosmological models obtained in f(T) gravity theory.The behaviour of the models based on the evolution of the equation of state parameter SUPER SKINNY SERUM shows phantom-like behaviour at the present epoch.The scalar perturbation technique is used to create the p
