Nanoparticle aggregation logic computing controlled by DNA branch migration

Cheng Zhang, Jingjing Ma, and Jing Yang et al.

In this work, nanoparticle aggregation is utilized to establish a nanoparticle computing system, and the computing process is triggered by adding specific DNA signals. Through DNA strand displacement, cascading regulations of aggregations are implemented. The logic computing operations of “OR” and ... [Appl. Phys. Lett. 103, 093106 (2013)] published Wed Aug 28, 2013.

Nano-superconducting quantum interference devices with continuous read out at milliKelvin temperatures

D. Hazra, J. R. Kirtley, and K. Hasselbach

We describe aluminum-niobium-tungsten trilayer Nano-Superconducting Quantum Interference Devices (NanoSQUIDs) that can be read out continuously down, in temperature, to at least 230 mK. They show voltage oscillations up to at least 20 mT in field. A voltage modulation of 500 μV, voltage sensitivit ... [Appl. Phys. Lett. 103, 093109 (2013)] published Wed Aug 28, 2013.

Field effect transistors with layered two-dimensional SnS2−xSex conduction channels: Effects of selenium substitution

T. S. Pan, D. De, and J. Manongdo et al.

A thorough characterization of field effect transistors with conduction channels made of SnS2−xSex nanocrystals having different selenium content is presented. The main effect of increasing the selenium content is a suppression of the drain-source current modulation by the gate voltage. The temper ... [Appl. Phys. Lett. 103, 093108 (2013)] published Wed Aug 28, 2013.

Absolute second order nonlinear susceptibility of Pt nanowire arrays on MgO faceted substrates with various cross-sectional shapes

Yoichi Ogata and Goro Mizutani

We have measured optical second harmonic generation (SHG) intensity from three types of Pt nanowires with 7 nm widths of elliptical and boomerang cross-sectional shapes and with 2 nm width elliptical cross-sectional shapes on the MgO faceted templates. From the SHG intensities, we calculated the a ... [Appl. Phys. Lett. 103, 093107 (2013)] published Wed Aug 28, 2013.
