We have fabricated light emitting diodes based on a conjugated polymer, in which a planarized two-dimensional photonic crystal (PC) was inserted between the glass substrate and the ITO anode. Planarized PCs were fabricated into a high-index layer via

Fluorene-based copolymers are currently attracting considerable interest for use in a wide range of optoelectronic devices. Here, we present the results of a joint quantum-chemical and experimental characterization of the structural, electronic, and

We show that the presence of InAs dots embedded in a host GaAs quantum well containing a two-dimensional electron gas dramatically modifies the cyclotron resonance (CR). Far-infrared CR measurements show two modes with different dispersions with appl

In this paper, we discuss the effect of a strong perpendicular magnetic field component upon a range of coupled double quantum well (CDQW) devices. With increasing inter-layer tunnelling, we observe a transition from double- to single-layer character

Schottky collector resonant-tunneling diodes (SCRTD's) have potential for increased oscillator bandwidth, but may be prone to electron reflection at the semiconductor-metal interface of the Schottky collector. This reflection has been observed previo

A high mobility coupled double-quantum-well structure is used to study distortions in the Fermi surfaces as a function of in-plane field and perpendicular field. The longitudinal resistance is measured with a fixed perpendicular field component while
