Trapping and identifying single-nanoparticles using a low-aspect-ratio nanopore

Makusu Tsutsui, Yoichi Maeda, and Yuhui He et al.

Manipulation of particles and molecules in fluid is a fundamental technology in biosensors. Here, we report electrical trapping and identification of single-nanoparticles using a low-aspect-ratio nanopore. Particle trapping and detrapping are implemented through a control of the cross-membrane ele ... [Appl. Phys. Lett. 103, 013108 (2013)] published Tue Jul 02, 2013.

Direct deposition of aluminum oxide gate dielectric on graphene channel using nitrogen plasma treatment

Taekyung Lim, Dongchool Kim, and Sanghyun Ju

Deposition of high-quality dielectric on a graphene channel is an essential technology to overcome structural constraints for the development of nano-electronic devices. In this study, we investigated a method for directly depositing aluminum oxide (Al2O3) on a graphene channel through nitrogen pl ... [Appl. Phys. Lett. 103, 013107 (2013)] published Tue Jul 02, 2013.

The charged exciton in an InGaN quantum dot on a GaN pyramid

Chih-Wei Hsu, Evgenii S. Moskalenko, and Martin O. Eriksson et al.

The emission of a charged exciton in an InGaN quantum dot (QD) on top of a GaN pyramid is identified experimentally. The intensity of the charged exciton exhibits the expected competition with that of the single exciton, as observed in temperature-dependent micro-photoluminescence measurements, pe ... [Appl. Phys. Lett. 103, 013109 (2013)] published Tue Jul 02, 2013.
