Prof. Wei Lu has published the book, Semiconductor Nanowires : From Next-Generation Electronics to Sustainable Energy. It is part of the Royal Society of Chemistry’s Smart Materials series, and co-edited by Prof. Jie Xiang from the University of California, San Diego.

Semiconductor nanowires were initially discovered in late 90’s and since then there has been an explosion in the research of their synthesis and understanding of their structures, growth mechanisms and properties. The realisation of their unique electrical, optical, and mechanical properties has led to a great interest in their use in electronics, energy generation, and storage.

Prof. Lu’s book provides a reference on semiconductor nanowires, including an introduction to their synthesis and properties and specific chapters focusing on their different applications. These include photovoltaics, nanogenerators, transistors, biosensors, and photonics. This is the first book dedicated to Semiconductor Nanowires and provides a resource for researchers working in the area, those new to the field, and for individuals interested in commercial applications.

Prof. Lu has been working on semiconductor nanowires since 2003. Among his achievements in nanowire research include the development of Ge/Si core/shell heterostructure nanowires and their applications, the synthesis and application of n-type Si nanowires, metal/semiconductor nanowire heterostructures, nanowire-based nanoelectromechanical systems, and the growth and applications of transparent conducting oxide nanowires. Currently his group works on the development of vertical nanowire transistors and photodetectors, and memory and logic devices based on two-terminal resistive switches (memristors).

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
