We report on the effects of a global top gate on low-frequency noise in Schottky gate-defined quantum point contacts (QPCs) and quantum dots (QDs) in a modulation-doped Si/SiGe heterostructure. For a relatively large top gate voltage, the QPC current shows frequent switching with 1/f2 Lorentzian t ...[Appl. Phys. Lett. 102, 123113 (2013)]published Fri Mar 29, 2013.
We report the effect of surface plasmons of silver nanowires (AgNWs) on the generation of hot electrons. The AgNWs were deposited on ultra-thin Au/TiO2 Schottky nanodiodes using a spraying method. As surface coverage of the AgNWs on the thin gold film increased, the short-circuit current under ill ...[Appl. Phys. Lett. 102, 123112 (2013)]published Fri Mar 29, 2013.
Selective etching of pre-stressed multi-layered structures releases intrinsic stresses creating flexible microscopic shapes (rolls, spirals, tubes, etc.). A question of major interest is how to control design, composition, and etching process in order to obtain a prescribed macroscopic object? We ...[Appl. Phys.

The plasmon resonance-induced near electric field focusing and enhancement of three-layered silver nano-cylinder has been studied by quasi-static electricity. A field enhancement factor of more than 102 times can be obtained in the middle dielectric wall between the inner silver wire and outer tub ...[Appl. Phys.

Vector magneto-optical generalized ellipsometry is employed for the determination of the three-dimensional magnetization properties of magnetized thin solid as well as slanted columnar thin film samples. The permalloy thin films were probed by means of Mueller matrix ellipsometry at room-temperatu ...[Appl. Phys. Lett. 102, 123109 (2013)]published Thu Mar 28, 2013.
A tip-enhanced Raman scattering (TERS) microscope has been developed, which is based on the tapping-mode operation of atomic force microscopy. By synchronizing a multichannel detector with tapping oscillation of the metallic nanotip, one can measure a tip-sample separation dependent TERS spectrum ...[Appl. Phys. Lett. 102, 123110 (2013)]published Thu Mar 28, 2013.
Electrically activated doping of boron (B) atoms into the Si-nanocrystals (Si-NCs) embedded silicon oxide film is achieved by co-sputtering technique following with the annealing treatment. The evolution of the size, the shape, and the density of Si-NCs with the doping of B atoms is investigated. ...[Appl. Phys. Lett. 102, 123108 (2013)]published Thu Mar 28, 2013.
