Figure 5From: Novel optoelectronic devices based on single semiconductor nanowires (nanobelts)FESEM image and room-temperature I - V characteristic of as-fabricated GNR/CdS NW heterojunction LED. (a) FESEM image of an as-fabricated GNR/CdS NW heterojunction LED. (b) Room-temperature I-V characteristic of the LED in (a) on a semilog scale. The red straight line shows the fitting result of the I-V curve by the equation ln I = q V n k T + ln I 0 .Back to article page
