Red-, orange-, and green-emitting integrated optoelectronic sources are demonstrated by transfer printing blue InGaN µLEDs onto ultra-thin glass platforms functionally enhanced with II-VI colloidal quantum dots (CQDs). The forward optical power conv

SiGe/Si multiple quantum wells, nominally 4 nm thick, were grown by low pressure chemical vapor deposition and the Ge distribution within the wells was studied using a variety of transmission electron microscope-based techniques. Energy-dispersive x-

Low-temperature mobilities for two-dimensional electron gases (2DEGs) formed in tensile-strained Si/SiGe heterostructures are reported, with values up to for a density of electrons. The strained layers were grown at in a ultra-high-vacuum chemical va

Laser etching of Co, Ni and Fe films, in conjunction with the pyrolysis of solid organic precursors (e.g. aminodichlorotriazine, melamine, etc.) generates aligned carbon nanotube bundles and films of uniform length (< 200 mu m) and diameter (30 Angst

In recent years the growth of virtual substrates using graded SiGe buffer layers has shown great promise for the development of high performance devices. Whilst significant progress has been made in the control of growth conditions to produce low thr

A case study is presented in which HREM, Z-Contrast Imaging and EELS are used as complementary techniques for elucidating interface structure. The NiO-ZrO2(cubic) interface is investigated along two orthogonal directions by these electron imaging and

GaAs nanocrystals have been formed by the sequential ion implantation method. The sequence of Ga and As ion implantation (i.e., Ga + As or As + Ga) is found to affect the size distributions of GaAs nanocrystals significantly. The nanocrystal sizes ar

The epitaxial growth of dissimilar materials, or hetroepitaxy, is of great technological interest for a variety of reasons. Perhaps the most obvious of these is that high quality, large area substrates are unavailable for many materials. It is theref

The low temperature electrical properties of modulation-doped two dimensional electron gases (2DEGs) in the SiGe system were studied. The effects on the electrical properties of removing the substrate from the growth chamber after the growth of the v
