Low-Frequency Contact Noise of GaN Nanowire Device Detected by Cross-Spectrum Technique

Gas Sensing with Bare and Graphene-covered Optical Nano-Antenna Structures

“…Researchers employ sensing materials that are sensitive to the gas, which can be a 1-D material like nanowires 4 and nanotubes 5 , or it can be a 2-D material like graphene 1 , or bulk type materials. However, there can be disadvantages associated with sensors based on 1-D materials, such as the noise and resistance introduced by the contacts 6 , operation at elevated temperature for better selectivity 7 , and the use of dielectrophoresis for alignment in case of 1-D materials 4 .…”
