Investigating single-walled carbon nanotube films for LEDs and lasers

Carbon nanotubes (CNT) offer interesting optoelectronic properties including engineered conductivity and tunable infrared emission. CNTs have been extensively studied as carrier transport layers for OLEDs or as single-nanotube LEDs. Here, we investigate LED and laser architectures using CNT films as a bulk active emitter layer tunable in the near IR. We investigate the intrinsic stability of the emitter layer and optimize device structure.
