Low-dimensional ZnO, possessing well-defined side facets and optical gain properties, has emerged as a promising material to develop ultraviolet coherent light sources. However, the realization of ...

We propose a tunable metamaterial absorber (MA) unit equipped with varactor and PIN diodes that is insensitive to polarization, aiming to significantly expand the metamaterial absorbers tunable ...

The research on high power 190 GHz doubler based on the GaAs Schottky diodes is proposed in this paper. The frequency doubler comprises a improved diode configuration that increases the number of ...

Root canal irrigants are used to minimize the negative effects of smear layer on endodontic sealer retention. The aim of this study was to evaluate the efficacy of agitation of 17% ...

Programmable and nonvolatile Schottky junctions are highly desirable for next-generation electronic and neuromorphic systems. However, conventional metal–semiconductor and even van der Waals (vdW) ...
