Journal ArticleDOI

Porous silicon: a quantum sponge structure for silicon based optoelectronics

Olmes Bisi, +2 more
- 01 Apr 2000 - 
TL;DR: The photoluminescence properties of porous silicon have attracted considerable research interest since their discovery in 1990 as discussed by the authors, which is due to excitonic recombination quantum confined in Si nanocrystals which remain after the partial electrochemical dissolution of silicon.
Journal ArticleDOI

Second-harmonic generation in silicon waveguides strained by silicon nitride

Massimo Cazzanelli, +12 more
- 01 Feb 2012 - 
TL;DR: It is shown that a sizeable second-order nonlinearity at optical wavelengths is induced in a silicon waveguide by using a stressing silicon nitride overlayer and envisage that nonlinear strained silicon could provide a competing platform for a new class of integrated light sources spanning the near- to mid-infrared spectrum from 1.2 to 10 μm.

Light Emitting Silicon for Microphotonics

Stefano Ossicini, +2 more
TL;DR: In this paper, the authors present a detailed analysis of the properties of contained Silicon Structures and present a future outlook for the future of these structures. But they do not discuss the future outlook of these materials.
Journal ArticleDOI

Role of the interface region on the optoelectronic properties of silicon nanocrystals embedded in SiO 2

Nicola Daldosso, +13 more
- 29 Aug 2003 - 
TL;DR: In this paper, the interface between the silicon nanocrystals and the surrounding is not sharp: an intermediate region of amorphous nature and variable composition links the crystalline Si with the amorphus stoichiometric, and this region plays an active role in the light-emission process.
Journal ArticleDOI

Self-energy and excitonic effects in the electronic and optical properties of TiO 2 crystalline phases

Letizia Chiodo, +8 more
- 22 Jul 2010 - 
TL;DR: In this article, a unified ab initio study of electronic and optical properties of TiO rutile and anatase phases with a combination of density-functional theory and many-body perturbation-theory techniques is presented.
