Abstract: A InGaP/InGaAs/GaAs dual channel pseudomorphic HEMT (DC- PHEMT) with interesting triple doped sheets having gate length 800nm is modeled and simulated by using 2-dimensional simulation package ATLAS fromSilvaco. Different DC and microwave performances of the above device are analyzed and investigated to judge the potential of the device for high- performance digital device applications. Due to the schottky behavior of InGaP, good pinch-off and saturation characteristics, high drain saturation current, large and linear transconductance and excellent microwave characteristics are obtained. The studied dual channel HEMT with delta-doped sheet densities and proper layers; prove promise for electronic applications.

Abstract: It has been shown that the addition of nano composites to the enamel can greatly improve the thermal, mechanical and electrical properties of enamel. A nano composite (TiO2+SiO2) has been tested as nano filler. The micro particles of TiO2 and SiO2 are converted into nano particles with the help of ball mill. Scanning electron microscope (SEM) has been used to augment the particle size of nano composite. The nano sio2 and tio2 materials taken in the ratio of 1:3 were mixed with enamel by using ultrasonic vibrator. The enamel filled with nano composite was coated on the windings of a motor. The values of electromagnetic inference produced by normal induction motor and nano coated induction motor was measured and analyzed. There was a reduction of 15 to 60% in the values of the electromagnetic interference produced by the normal induction motor when compared to that of nano composite filled enamel coated induction motor at various distances. Hence, the nano composite filled enamel coated
