Experimental investigation on solidification behavior of water based CNT nanofluids for cool thermal storage system

Kumaresan V., Anna University, IN

Nano-enhanced phase change material (NEPCM) was prepared by two step method using distilled water as the base fluid, sodium dodecyl benzene sulphonate (SDBS) as a surfactant, pseudomonas as nucleating agent and multi-walled carbon nanotubes (MWCNT) [...]

On the investigation of an interdigitated, high capacitance ratio shunt RF-MEMS switch for X- band applications

Angira M., BITS PILANI, IN

This paper presents a novel, highly compact capacitive shunt RF MEMS switch. In the presnted switch, interdigitation of signal lines with actuation electrodes. are used. The compactness has been achieved further by incorporating the HfO2 [...]

Experimental study on sheet resistivity and thickness measurement in Copper Electroplating

Sharma A., Kumar D., Kumar Khandelwal S., Bansal D., Rangra K., Kumar D., Kumar Khandelwal S., Central Electronics Engineering Research Institute (CEERI/ CSIR), IN

Electroplated copper thin films have been extensively used for interconnections in semiconductor devices. In this paper, electroplating of copper has been investigated to study the dependency of plated film thickness, current efficiency and sheet resistivity [...]

Electro-thermal aspects in carbon based interconnects

Verma R., Bhattacharya S., Mahapatra S., Indian Institute of Science, IN

The tremendous rise in Joule-heating in conventional ICs has led down ITRS to ensure on material alternatives that surpasses break-down current density and thermal conductivity (κ) beyond room temperature (RT). In recent years, suspended metallic [...]

Doping-less Bipolar Transistor with fT Surpassing that of Conventional BJT

Nadda K., Jagadesh Kumar M., Indian Institute of Technology Delhi, IN

An innovative ultrathin SOI based bipolar charge plasma transistor BCPT for RF circuit applications is presented in this paper. The proposed device structure exhibits high cut-off frequency and an improved current drive while still maintaining [...]

A Novel Technique for Depositing Vertically Aligned Molybdenum Oxide Nanoplates

Sharma R.K., Reddy G.B., Indian Institute of Technology Delhi, IN

Single crystalline, vertically aligned nanoplates of molybdenum trioxide (MoO3) were grown on the cobalt coated glass substrates by a simple sublimation process in the presence of oxygen plasma. Many research groups have reported the synthesis [...]

Novel, Flexible and Low-power Driven AC Electroluminescent Lamp from Carbon Nanotube Embedded Phosphor Material

Haranath D., Yadav D., Sahai S., Shanker V., CSIR-National Physical Laboratory, IN
