Temperature-dependent electrical and photo-sensing properties of horizontally-oriented carbon nanotube networks synthesized by sandwich-growth microwave plasma chemical vapor deposition

► Horizontally-oriented interconnected carbon nanotube networks (CNT-NWs) were grown. ► A microwave plasma chemical vapor deposition sandwich-growth process was employed. ► Temperature-dependent electrical and photo-sensing properties were investigated. ► Devices based on CNT-NWs exhibit promising transistor characteristics. ► CNT-NWs are capable to detect light in the infrared wavelength range.
