Enhanced electroluminescence (EL) has been achieved from the light-emitting devices containing Si quantum dots/SiO2 multilayers deposited on Si nanowire arrays because of the good antireflection characteristics of Si nanowire structures, which improves the light extraction efficiency. However, it is found that the EL is first enhanced with increasing the depth of the Si nanowires and then reduced...
This paper reports the fabrication, measurement and discussion about the nanosolenoid inductors for high frequency applications as much as 40 GHz, taking advantage of a much smaller size compared with traditional microinductors. Three small size nanosolenoid inductors are fabricated, such as a nanosolenoid inductor with a diameter of 4.8 um, pitch of 10 um, length of 22 um. The nanohelix inductors...
We report a novel microfluidic surface-enhanced Raman scattering (SERS) device, which is achieved by bonding a polydimethylsiloxane cap with a microchannel structure onto an SERS-active substrate composed of noble-metal covered silicon nanopillar forests. The silicon nanopillar forests are fabricated by using nanomaterial dots, which are introduced in oxygen-plasma bombardment of photoresist, as etching...
We report for the first time a facile lithography-free approach for fabricating nanopillars over large areas or in patterns. The key technique of this approach is that randomly-distributed nanoscale SiO2 patterns can be synthesized on substrates simply by removing photoresist with oxygen plasma bombardment. Those SiO2 nanopatterns may further function as masks in the following etching process for...
