نویسندگان

چکیده

A kind of Zinc oxide (ZnO)/Cadmium sulfide (CdS)/Silica nanopillars structure is fabricated to photoresistor for the first time. The silica wafer with countless used as substrate photoresistor. CdS and ZnO film are deposited by frequency (RF) magnetron sputtering onto surface form ZnO/CdS/Silica structure. nanowires also can grow on hydrothermal reaction nanowires/CdS/Silica structures. X-ray diffraction curves show that both planar nanopillar well-crystallized. deposition reduce reflection increase absorption incoming light, especially light a wavelength less than 350 nm. And ZnO/CdS heterojunction retard recombination probability photon-generated carries prolong lifetime carriers, which lending remarkable photocurrent improvement. photosensitivity property testing results has best response 135 white 10 mW/cm2 illumination.

HSQ-Based Fabrication of Magnetic Nanopillars

Hydrogen silsesquioxane (HSQ) has been used as e-beam resist and ion milling mask in the fabrication of spin valve devices. The excellent performance of HSQ in patterning nanometer size features and corresponding procedures such as chemical mechanical polishing (CMP) make the HSQ-based process a reliable and economic way to make nanomagnetic devices.

Fabrication, structure and mechanical properties of indium nanopillars

Solid and hollow cylindrical indium pillars with nanoscale diameters were prepared using electron beam lithography followed by the electroplating fabrication method. The microstructure of the solid-core indium pillars was characterized by scanning micro-X-ray diffraction, which shows that the indium pillars were annealed at room temperature with very few dislocations remaining in the samples. T...

Parallel fabrication of magnetic tunnel junction nanopillars by nanosphere lithography

We present a new method for fabricating magnetic tunnel junction nanopillars that uses polystyrene nanospheres as a lithographic template. Unlike the common approaches, which depend on electron beam lithography to sequentially fabricate each nanopillar, this method is capable of patterning a large number of nanopillars simultaneously. Both random and ordered nanosphere patterns have been explor...
