Graphene has excellent properties that are useful in many electronic device applications. In this report, a mechanical exfoliation method has been used to fabricate a field-effect device based on a thin film of few-layer graphene (FLG). The occurrence of p-doping and hysteresis in the current-voltage behavior was observed and characterized. The possible(More)
A revolution to illumination industry, the high power light emitting diodes, LEDs have significant dominance in terms of optical performance, low power consumption and superior reliability over conventional lights. In spite of that the junction temperature of the LED is an imperative aspect which manipulates the consistency of the LED. This study discusses(More)
LEDs are being utilized as lighting source due to its superior advantages over incandescent lamps in terms of higher efficiency, brighter light emission and longer lifetime. However, the reliability and efficiency of the LED is dependent on the junction temperature of the LED chip. Hence, the heat dissipation of single chip LED package with aluminum heat(More)
