We report for the first time on an aluminum nitride/gallium nitride (AlN/GaN) heterostructure as a microscale Hall effect sensor current sensing applications in extreme environments. The AlN/GaN devices demonstrated high signal linearity function of magnetic field across temperature range from <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$-$</tex-math> </inline-formula> 193...
We report the studies relating to fabrication of an efficient immunosensor for Vibrio cholerae detection. Magnetite (iron oxide (Fe(3)O(4))) nanoparticles (NPs) have been synthesized by co-precipitation method and capped citric acid (CA). These NPs were electrophoretically deposited onto indium-tin-oxide (ITO)-coated glass substrate used immobilization monoclonal antibodies against (Ab) bovine serum albumin (BSA) detection using electrochemical technique. The structural morphological...
Topological semimetals possess nodal or nodal-line phases where conduction and valence bands touch at points lines in momentum space, respectively. Such band touching is symmetry protected gives rise to exotic interesting electronic properties. Coupling topological order with magnetism provides a platform for exploring time-reversal (TR) breaking physics, such as axion electrodynamics, inverse spin-galvanic effect, the quantized anomalous Hall effect. The Weyl semimetal (WSM) requires either...
The study aimed to investigate the underlying physics limiting temperature stability and performance of non-surface passivated Al0.34Ga0.66N/GaN Hall effect sensors, including contacts, under atmospheric conditions. results obtained from analyzing microstructural evolution in sensor heterostructure were found correlate with electrical sensor. High-resolution x-ray photoelectron spectroscopy studies revealed signature surface oxidation GaN cap layer, as well a slight out-diffusion “Al” AlGaN...
High-quality InN has significant opportunities for exciting and impactful electronic photonic applications. These applications rely on growth techniques that produce high-quality thin films. To achieve the fabrication of semiconductor films with a low density misfit threading dislocations, we report technique utilizes composition strain gradients to limit propagation defects into grown GaN/sapphire substrate. The have investigated compressively strained gradient transition layer dislocations...
To meet the areal density growth (∼60% compound annual rate) challenge in disk drive industry, track (tracks per inch, TPI) has been increasing at ∼30% rate. As increases, size of erase band, unless controlled, becomes a significant portion written track. In this work, special equipment was developed to study (i) bands, (ii) effect pole trimming on band and hooks, (iii) anisotropy bands (iv) hooks high TPI. We demonstrated servo pattern writing reading capability (through preamp channel)...
