摘要： The present invention provides the multifunctional biological and biochemical sensor technology based on ZnO nanostructures. The ZnO nanotips (12) serve as strong DNA or protein molecule binding sites to enhance the immobilization. Patterned ZnO nanotips are used to provide conductivity-based biosensors (10). Patterned ZnO nanotips are also used as the gate (26) for field-effect transistor (FET) type sensors (20). Patterned ZnO nanotips are integrated with SAW (30) or BAW (56) based biosensors. These ZnO nanotip based devices operate in multimodal operation combining electrical, acoustic and optical sensing mechanisms. The multifunctional biosensors can be arrayed and combined into one biochip, which will enhance the sensitivity and accuracy of biological and biochemical detection due to strong immobilization and multimodal operation capability. Such biological and biochemical sensor technology are useful in detection of RNA-DNA, DNA-DNA, protein-protein, protein-DNA and protein-small molecules interaction. It can be further applied for drug discovery, and for environmental monitoring and protection.

摘要： In the present invention, there is provided semiconductor devices such as a Schottky UV photodetector fabricated on n-type ZnO and Mg x Zn 1-x O epitaxial films. The ZnO and Mg x Zn 1-x O films are grown on R-plane sapphire substrates and the Schottky diodes are fabricated on the ZnO and Mg x Zn 1-x O films using silver and aluminium as Schottky and ohmic contact metals, respectively. The Schottky diodes have circular patterns, where the inner circle is the Schottky contact, and the outside ring is the ohmic contact. Ag Schottky contact patterns are fabricated using standard liftoff techniques, while the Al ohmic contact patterns are formed using wet chemical etching. These detectors show low frequency photoresponsivity, high speed photoresponse, lower leakage current and low noise performance as compared to their photoconductive counterparts. This invention is also applicable to optical modulators, Metal Semiconductor Field Effect Transistor (MESFETs) and more.
