Materials for Optoelectronics

To appear in “Noncrystalline materials for Optoelectronics”,

In this paper, we review some recent work on amorphous materials using current “first principles” electronic structure/molecular dynamics techniques. The main theme of the paper is to emphasize new directions in the use of such ab initio methods. Some of these, being quite new, need development, but we believe have promise for solving new and important kinds of problems in the physics of glassy...

Integration of 2D materials on a silicon photonics platform for optoelectronics applications

Owing to enormous growth in both data storage and the demand for high-performance computing, there has been a major effort to integrate telecom networks onchip. Silicon photonics is an ideal candidate, thanks to the maturity and economics of current CMOS processes in addition to the desirable optical properties of silicon in the near IR. The basics of optical communication require the ability t...

Conjugated-Polymer Blends for Optoelectronics

Solution-processed polymer optoelectronic devices such as light-emitting diodes and solar cells have many advantages for large-area manufacture, and show increasing levels of performance. Here, we review recent progress in using blends of two conjugated polymers for optoelectronic devices. The blending of two or more polymers allows tuning of device performance, and for photovoltaics presents a...

Optoelectronics: Combining chemical worlds.

A goal of molecular materials chemistry is to develop synthetic strategies for the precise placement of molecular building blocks at nano-and mesoscale levels. If the building blocks comprise both organic and inorganic moieties, the resultant hybrid composites have the advantage of combining complementary strengths from two different chemical worlds. By piecing together a judicious choice of th...
