Electronic confinement at nanoscale dimensions remains a central means of science and technology. We demonstrate nanoscale lateral confinement of a quasi-two-dimensional electron gas at a lanthanum aluminate-strontium titanate interface. Control of this confinement using an atomic force microscope lithography technique enabled us to create tunnel junctions and field-effect transistors with char...

Featured Article: Zheng GF, Patolsky F, Cui Y, Wang WU, Lieber CM. Multiplexed electrical detection of cancer markers with nanowire sensor arrays. Nat Biotechnol 2005;23:1294–301. There are 200 types of cancers, each with many variants. The devastating effects of cancer on patients and their families extract a huge loss. For instance, nearly 1.5 million people in the US alone are diagnosed with...

The quantum mechanical functionality of nanoelectronic devices such as resonant tunneling diodes (RTDs), quantum well infrared photodetectors (QWIPs), quantum well lasers, and heterostructure fieM effect transistors (HFETs) is enabled by material variations on an atomic scale. The design and optimization of such devices requires a fundamental understanding of electron transport in such dimensio...

1. Introduction Two pioneering papers on the 2D (two-dimensional) carbon-based material graphene published in 2004 [1-2] ignited an enormous attention to this material and it did not take long before the electron device community showed interest in graphene [3-5]. Mainly graphene's excellent carrier transport properties have attracted device engineers and led to the expectation that graphene co...

T breath-taking increase in performance of nanoelectronic circuits has been continuously supported by the uninterrupted miniaturization of devices and interconnects. Among the most crucial technological changes lately adopted by the semiconductor industry is the introduction of a new type of multi-gate three-dimensional (3D) transistors [1]. This technology combined with strain techniques and h...

Nanophotonics, Nanoelectronics and Nanosensor (N3) is part of International Photonics and OptoElectronics Meetings (POEM), launched by Wuhan National Laboratory for Optoelectronics (WNLO). POEM is a large-scale multi-disciplinary international conference in the field of photonics and optoelectronics. It aims to focus on the key techniques of scientific frontier and industry in the field of opto...

Carbon nanotubes (CNTs) have emerged as a viable electronic material for molecular electronic devices because of their unique physical and electrical properties [1–7]. For example, nanotubes have a lightweight and record-high elastic modulus, and they are predicted to be by far the strongest fibers that can be made. Their high strength and high flexibility are unique mechanical properties. They...
