Abstract

AbstractGraphene flakes were made from electrochemical exfoliation. To study graphene planes, different volumes of graphene solutions (1, 2, 4, and 7 ml) were sprayed on glass lamellae to get different graphene planes. IâV curve of all samples shows ohmic behavior with resistance in the order of kΩ which increases the slope of the IâV curve with increasing graphene planes (spray volume). The effect of temperature on all samples shows a clear jump in IâT curves. It is found that up to 150 °C current is almost constant, but after that current increases highly in the range of 1.8â10 times and resistance reduces sharply. Also, samples with lower graphene planes affected highly with temperature effect.
