We have measured the infrared properties of optically transparent and electrically conductive single walled carbon nanotube thin films. We found that nanotube films with sheet resistance values of 200 ࡎ/sq show outstanding transmittance in the infrared range up to at least 22 μm, with an average transmittance greater than 90% over this range. The infrared properties of various materials were compared and we found that transparent nanotube electrodes and transparent graphene electrodes outperform the others in several key categories. This study opens another important application area for conductive nanotube thin films.

    We report on the electroforming in resistively switching nanocrosspoint devices made of a reactively sputtered TiO2 thin film between Pt and Ti/Pt electrodes, respectively. As most resistance switching materials, TiO2 needs to be electroformed before it can be switched. This paper presents and...

    Thin film transistors are fabricated by in situ growth of SnO2 nanobelts on Au/Pt electrodes. A linear correlation in the output characteristics is observed at zero gate voltage, indicating Ohmic contacts between the nanobelts and the electrodes. The transistors exhibit n-type behaviors and have...
