Top-down method was used to fabricate zinc oxide (ZnO) nano wire field effect transistor (NWFET) biosensor. The nanosensor was used to measure the electrical characteristics of lysozyme (LYSO) and bovine serum albumin (BSA) protein solutions in phosphate buffered saline (PBS). The LYSO and BSA proteins are oppositely charged at measurement pH of 7.4. Subthreshold voltage shift of 340 mV and 700 mV...
Zinc oxide nanorods have great potential for the realization of high efficiency heterostructure LEDs based on p-doped gallium nitride. In order to obtain a good confinement of the light, a well-aligned nanorod waveguiding structure is desirable. This paper reports on the fabrication of vertical zinc oxide nanorods using a solution-based growth process that does not require a seed layer. The nanorods...
Zinc oxide structures with size in the micro and nano-scale range represent key candidates for developing novel, cheap and efficient electronic devices, power generators and sensors based on the cooperative response of a large number of synced structures. The accurate electrical characterization of single ZnO micro/nanostructures is thus critical for assessing and optimizing the device performance...
Nowadays, flexible and transparent electronics are receiving much attention in industry and research groups. Aiming at a suitable device for this technology, we present a low-cost and low-temperature integration process for ZnO nanoparticle thin-film transistors using a spray coating technique. An inverted coplanar structure with high-k gate dielectric filled with TiO2 nanoparticles is used as transistor...
