Nanowire Optoelectronics

Superenhancers: Novel opportunities for nanowire optoelectronics

Nanowires play a crucial role in the development of new generation optoelectronic devices ranging from photovoltaics to photodetectors, as these designs capitalize on the low material usage, utilize leaky-mode optical resonances and possess high conversion efficiencies associated with nanowire geometry. However, their current schemes lack sufficient absorption capacity demanded for their practi...

Aligned silver nanowire-based transparent electrodes for engineering polarisation-selective optoelectronics

We herein report on a remarkably simple, fast, and economic way of fabricating homogeneous and well oriented silver nanowires (AgNWs) that exhibit strong in-plane electrical and optical anisotropies. Using a small quantity of AgNW suspension, the horizontal-dip (H-dip) coating method was applied, in which highly oriented AgNWs were deposited unidirectionally along the direction of coating over ...

Droop-Free, Reliable, and High-Power InGaN/GaN Nanowire Light-Emitting Diodes for Monolithic Metal-Optoelectronics.

A droop-free nitride light-emitting diode (LED) with the capacity to operate beyond the "green gap" has been a subject of intense scientific and engineering interest. While several properties of nanowires on silicon make them promising for use in LED development, the high aspect ratio of individual nanowires and their laterally discontinuous features limit phonon transport and device performanc...

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...
