Item Open Access Determination of Plasma Temperature of Copper Vapour laser(Cambridge University Press, 2016) Namnabat, M.; Behrouzinia, S.; Moradi, A. R.; Khorasani, K.The output power and the temperature profile of a copper vapour laser were investigated versus frequency with various kinds of back mirror in its resonator cavity. A semi-experimental method was used for measuring the plasma temperature and obtaining the temperature profile with various back mirrors. The obtained plasma temperature through this method has good agreement with the operational temperature of the laser.Item Open Access Operation of carbon nanotube thin-film transistors at elevated temperatures(IEEE, 2009-12) Öztürk, Sadi; Doğan, Mustafa; Aktaş, ÖzgürThe authors study the operation of carbon nanotube thin-film transistors (CNT-TFT) at elevated temperatures. Due to the small bandgap of semiconducting carbon nanotubes, CNT-TFTs are not suitable to be developed as high-temperature devices. However, CNT-TFTs will still have to endure elevated temperatures when employed in large-area and flexible electronic applications. The temperature range that can be expected in these applications is well below 100°C. In this work, the authors demonstrate that even at 100°C, CNT-TFT devices are operational but with a reduced ON/OFF ratio. Beyond 100°C, the ON/OFF ratio degrades rapidly.
