    Abstract: Heterojunctions of single-walled carbon nanotubes and p-doped silicon produce a photocurrent when irradiated with visible light under reverse bias conditions. In optoelectronic devices utilizing the heterojunctions, the output current can be controlled completely by both optical and electrical inputs. The heterojunctions provide a platform for heterogeneous optoelectronic logic elements with high voltage- switchable photocurrent, photo- voltage responsivity, electrical ON/OFF ratio, and optical ON/OFF ratio. The devices are combined to make switches, logic elements, and imaging sensors. An assembly of 250,000 sensor elements on a centimeter-scale wafer is also provided, with each sensor element having a heterojunction of single-walled carbon nanotubes and p-doped silicon, and producing a current dependent on both the optical and the electrical input.

    Abstract: A carbon nanotube-based micron scale chemical sensor or sensor array is provided that enables the remote detection of hydrogen sulfide and other chemicals in a gas stream. The sensor is suitable for use in harsh environments of high temperature and pressure such as those encountered during petrochemical exploration and recovery. Multiplex sensor devices detect two or more chemical agents simultaneously, or they can detect conditions such as pressure, salinity, humidity, pH, or scale-forming ions. Incorporation of read out electronics and an RF signal generator into the sensor device enables it to communicate to a relay station or receiver for 3D mapping or other analysis. Methods are also provided for fabricating the chemical sensor device and using the device for detection.
