Abstract: In this work, we demonstrate an AlGaN-based deep-ultraviolet light-emitting diodes (DUV LEDs) structure with the incorporation of inverted-V-shaped quantum barriers (QBs). Intriguingly, the light output power (LOP) can be remarkably boosted by 157% in comparison… read more here.

DOI: 10.1117/1.jnp.14.016013
Abstract: Abstract. The binding energy, oscillator strengths, and absorption coefficients (ACs) for double ring-shaped quantum dots (DRSQDs) are theoretically investigated within the framework of effective mass approximation. The Schrödinger equation is solved by a variational method… read more here.
