Journal ArticleDOI
Coupling between two microstrip lines through apertures
TL;DR: In this article, an analysis of coupling between two microstrip transmission lines, coupled together through small apertures in the common ground plane, is presented, and the experimental results compare well with theory.
Journal ArticleDOI
Electrical transport studies of MBE grown InGaN/Si isotype heterojunctions
Mahesh Kumar,Mahesh Kumar,Basanta Roul,Basanta Roul,Mohana K. Rajpalke,Thirumaleshwara N. Bhat,A. T. Kalghatgi,S. B. Krupanidhi +7 more
TL;DR: The temperature dependent electrical transport behavior of n-n InGaN/Si heterostructures grown by plasma-assisted MBE was studied in this paper, where structural characteristics of the epilayers were evaluated high-resolution X-ray diffraction and composition of InGaNs was estimated from photoluminescence spectra using standard Vegard's law.
Journal ArticleDOI
Carrier-transport studies of III-nitride/Si3N4/Si isotype heterojunctions
Mahesh Kumar,Mahesh Kumar,Basanta Roul,Basanta Roul,Thirumaleshwara N. Bhat,Mohana K. Rajpalke,A. T. Kalghatgi,S. B. Krupanidhi +7 more
TL;DR: In this article, a comparison of the I-V characteristics of GaN/Si3N4/n-Si epilayers was performed using high-resolution X-ray diffraction and thickness of ultrathin Si 3N4 layer was measured by transmission electron microscopy.
Journal ArticleDOI
Improvement in the Sensing Response of Nano-Crystalline ZnO-Based Hydrogen Sensor: Effect of Swift Heavy Ion Irradiation
TL;DR: In this paper, X-ray diffraction reveals single crystalline wurtzite structure of nano-crystalline ZnO thin films, and the sensitivity was enhanced from 66.68% to 89.84% with fluence variations from pristine to $1\times 10^{12}$ ions/cm2 at 175 °C operating temperature.
Journal ArticleDOI
Plasmonic Au Nanoparticles Sensitized MoS₂ for Bifunctional NO₂ and Light Sensing
TL;DR: In this article, plasmonic Au nanoparticles functionalized MoS2 device showed about 5 times higher sensitivity to NO2 than that of pristine MoS 2 at room temperature, attributed to a combination of Schottky barriers modulation at Au/MoS2 nanointerfaces and catalytic effects upon exposing the gas analyte.
