Assessment of L-DUMGAC MOSFET for High Performance RF Applications with Intrinsic Delay and Stability as Design Tools

Chaujar R., Kaur R., Saxena M., Gupta M., Gupta R.S., Gupta M., Gupta R.S., Semiconductor Devices Research Laboratory, IN

The paper assesses RF performance of L-DUMGAC MOSFET using ATLAS device simulator by performing AC simulations at very high frequencies, hence, proving its efficacy for high performance RF applications. Higher Gma & K; and lower [...]

Modeling of Microcantilever based Nuclear Microbatteries

Sheeparamatti B.G., Sheeparamatti R.B., Kadadevarmath J.S., Sheeparamatti B.G., Sheeparamatti R.B., Basaveshwar Engineering College, IN

Microcantilevers are extremely versatile and are used as sensors, actuators and in many other microsystems. In this work, mathematical model of a microcantilever based actuator, which can be driven by nuclear radiation, is developed. This [...]

Optical properties of [001] GaN nanowires- An ab-initio study

Agrawal B.K., Agrawal S., Pathak A., Agrawal B.K., Agrawal S., Allahabad University, IN

We study the physical properties of the unpassivated and H-passivated GaN nanowires (NWs) by employing the first–principles pseudopotential method within density functional theory (DFT). Two types of the NW’s having hexagonal and triangular cross-sections have [...]

Nanostimulation in Brain and Emerging Imaging Capabilities

Sharma A., Sharma R., Sharma A., Sharma R., MP Agriculture and Engineering University, IN

With advent of nanoscale imaging technology available, possibly this dilemma may be solved by fusion of microimaging techniques like MRI/PET/CT/SPECT using smart imaging contrast materials.

Optical absorption and luminescence study of ZnS quantum dots

Chakdar D., Gope G., Talukdar A., Avasthi D.K., Nath S.S., Research Scholor, IN

We report here ZnS quantum dots synthesized by chemical method at room temperature. In this technique ZnS quantum dots are produced by simple chemical reactions where Zeolite, acting as matrix, plays the key role in [...]

Effect of swift heavy ion on CdS quantum dots embedded in PVA matrix and their applications

Gope G., Chakdar D., Avasthi D.K., Paul M., Nath S.S., NIT Silcchar, IN

We report synthesis of CdS quantum dots by chemical route at room temperature. In this technique CdS specimen are produced by simple chemical reactions where polyvinyl alcohol (PVA), acting as matrix, plays the key role [...]

Tunnel Field Effect Transistor (TFET) with Strained Silicon Thinfilm Body for Enhanced Drain Current and Pragmatic Threshold Voltage

Kumar M.J., Saurabh S., Indian Institute of Technology, IN

Quantum tunneling devices are very promising as they have very low leakage current and show good scalability. However, the most serious drawback for tunneling devices hampering their wide-scale CMOS application is their low on-current and [...]

Radiolabelled Microspheres As a Delivery System For Targetad Radiotherapy

Bandopadhyaya G.P., Shukla J., All India Institute of Medical Sciences, IN

99mTc(V)DMSA (Dimercaptosuccinic acid) is a well-known radiopharmaceutical for imaging neurogenic tumors. 188Rhenium, a beta radiation emitter with 2.2 MeV energy having half life of 16.9 hours is a therapeutic analogue of imagable 99mTechnetium was introduced [...]

Spatio-temporal Tumor Model for Analysis and Mechanism of action of Intracellular Drug Accumulation

Mishra S., Katiyar V.K., Arora V., Haridwar, IN

We have developed a one-dimensional tumor simulator to describe the biodistribution of chemotherapeutic drugs to a tumoral lesion and the tumor cell’s response to therapy. A three-compartment model is used for drug dynamics within the [...]
