PHOTONIC devices are becoming increasingly important in information and communication
technologies. But attempts to integrate photonics with silicon-based microelectronics are …

Adding optical functionality to a silicon microelectronic chip is one of the most challenging
problems of materials research. Silicon is an indirect-bandgap semiconductor and so is an …

LIGHT-emitting devices based on silicon would find many applications in both VLSI and
display technologies, but silicon normally emits only extremely weak infrared …

system because Si02 can be grown by exposing a silicon substrate heated to-550 C to
oxygen. Subsequently, silicon can be evaporated or even deposited epitaxially with a …

MICROELECTRONIC device integration has progressed to the point where
complete'systems-on-a-chip'have been realized1–3. Now that optoelectronics is becoming …

The possibility induction of light emission from silicon, an indirect bandgap material in which
radiative transitions are unlikely, raises several interesting and technologically important …

The widely used 'silicon-on-insulator'(SOI) system consists of a layer of single-crystalline
silicon supported on a silicon dioxide substrate. When this silicon layer (the template layer) …

Abstract Superlattices of Si/SiO 2 have been grown at room temperature with atomic layer
precision using state of the art molecular beam epitaxy and ultraviolet ozone treatment …

FOLLOWING reports of intense optical luminescence from porous silicon1, 2, the opportunity
for engineering optoelectronic devices using this material3, 4 has attracted considerable …
