Current density enhancement nano-contact phase-change memory for low writing current

You Yin, Sumio Hosaka, and Woon Ik Park et al.

In this work, a phase-change memory (PCM) with self-assembled nanostructures and an oxidized thin phase-change layer is proposed and intensively investigated for low writing reset current by finite element analysis. Current density is significantly enhanced in our nano-contact memory because of th ... [Appl. Phys. Lett. 103, 033116 (2013)] published Wed Jul 17, 2013.

Massively parallel aligned microfibers-based harvester deposited via in situ, oriented poled near-field electrospinning

Yiin-Kuen Fuh, Shao-Yu Chen, and Jia-Cheng Ye

In this study, we demonstrate a direct-write, in situ poled polyvinylidene fluoride power generator via near-field electrospinning and fully encapsulated on a flexible substrate. An unique polarity alignment and a total of 500 microfibers continuously deposited in parallel and serial configuration ... [Appl. Phys. Lett. 103, 033114 (2013)] published Wed Jul 17, 2013.

Fabrication and characterization of a large-area metal nano-grid wave plate

A. Kravchenko, A. Shevchenko, and V. Ovchinnikov et al.

We introduce a fast and cost-effective technique to fabricate large-area periodically nanopatterned metal samples and apply this technique to create reflective nano-grid wave plates for optical wavelengths. The technique makes use of azo-polymer-based interference lithography and a special imprint ... [Appl. Phys. Lett. 103, 033111 (2013)] published Wed Jul 17, 2013.

Local electron field emission study of two-dimensional carbon

Ying Wang, Yumeng Yang, and Zizheng Zhao et al.

A systematic field-emission study has been carried out on different types of two-dimensional carbons in ultrahigh vacuum with the cathode-anode distance ranging from near-contact to about 124 nm. An analytical model has been developed to explain the increase of field enhancement factor with the ca ... [Appl. Phys. Lett. 103, 033115 (2013)] published Wed Jul 17, 2013.

High-throughput formation and control of monodisperse liquid crystals droplets driven by an alternating current electric field in a microfluidic device

M. Belloul, J.-F. Bartolo, and B. Ziraoui et al.

We investigate the effect of an applied ac high voltage on a confined stable nematic liquid crystal (LC) in a microfluidic device and show that this actuation leads to the formation of highly monodisperse microdroplets with an unexpected constant mean size over a large interval of the forcing freq ...

Influence of the Purcell effect on the purity of bright single photon sources

V. Giesz, O. Gazzano, and A. K. Nowak et al.

Purcell effect is a powerful tool to efficiently collect single photons emitted by semiconductor quantum dots. However, it is common to observe a degraded single photon purity when a quantum dot is inserted in an optical microcavity. Here, we investigate the role of the cavity coupling on the sing ... [Appl. Phys. Lett. 103, 033113 (2013)] published Wed Jul 17, 2013.
