The updated Class 12th Physics syllabus for the academic year 2025-26 has been released by the Rajasthan Board on its ...

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 ...

A Zener diode model for use with circuit analysis programs is described, and the implementation of the model in SPICE2 is explained. Breakdown is modeled as a sum of one or two exponential terms. If ...

The as-fabricated violet GaN-based light-emitting diodes (LEDs) show high stability and high light output power (LOP). This work provides a general rule for the growth of high-quality and transferable ...

A novel microwave noise generator circuit using multiple Zener diodes connected in series was designed and tested. Measurements are presented up to 6 GHz. It is presented in this letter that when the ...
