Abstract :
In this work, we report the first electroluminescence results from suspended CNTFETs. We find not only an increase in quantum efficiency by 2-3 orders of magnitude, but a completely different dependence of the light emission on the electrical properties of the CNTFET. To fabricate a suspended CNTFET, we etched 2-10 mum wide trenches in 200 nm thick SiO2 on Si wafers
