We have studied the electrical and optical properties of thermal light emission in carbon nanotubes (CNTs). Aligned CNTs were synthesized by chemical vapor deposition on the ST cut single crystal quartz substrate and transferred on the predefined electrode with trench structures. A light emission phenomenon due to the joule heat occurs when a current flows through the suspended CNTs. A voltage was applied to the electrode pad to conduct a current-voltage characteristic and transport study. Based on these results, we found conditions for stable light emission in CNTs, and the optical and electrical properties changed by light emission were confirmed. Moreover, the details of device fabrication and possible application of our device will be suggested in this presentation.
