Effect of laser irradiation on the tribological properties of RFsputtered nickel oxide (NiO) thin films
Srikanth Itapu, Vamsi Borra, Frank X. Li +2
The present work aims at investigating the effect of laser irradiation on the tribological properties of RF-sputtered NiO thin films deposited on industrial grade aluminum substrat…
Laser-Based Fabrication of Microstructures on Nickel Thin Films and Its Applications in On-Chip Thin Film Inductors
Srikanth Itapu, Vamsi Borra, Daniel G. Georgiev
This work reports on the fabrication of microbump structures on Ni films by single-pulse, localized laser irradiation. Conditions for the reproducible formation of such microstruct…
Transient Thermal and Electrical Characteristics of a Cylindrical LiFeS2 Cell with Equivalent Circuit Model
Khaled I Alsharif, Alexander H Pesch, Vamsi Borra +4
This study examines the discharge behaviour of a cylindrical LiFeS2 cell to evaluate the parameters that can be used to predict and estimate the nonlinear dynamic response of a bat…
Harmonic content analysis of a soft starting variable frequency motor drive based on FPGA
Yogesh Sapkota, Suman Devkota, Vamsi Borra +3
As the demands for electric vehicles, electric aircrafts, unmanned aircraft systems, and other motor-driven systems increase, high-performance motor drives employing variable frequ…
Metal whisker growth induced by localized, high-intensity DC electric fields
Vamsi Borra, Osama Oudat, Daniel G. Georgiev +2
In this work, a very high, locally applied electric field was used to induce whisker nucleation on an Sn film. The field was generated by using a conductive AFM tip and applying a…
Sn whisker growth mitigation by using NiO sublayers
Vamsi Borra, Srikanth Itapu, Daniel G. Georgiev
The potential of NiO sublayers for whisker growth mitigation has been examined. A thin NiO film was applied on a Cu-coated substrate before the deposition of a thicker Sn layer. Th…
