Engineering impurity behavior on the micron-scale in metallurgical-grade silicon production
(Massachusetts Institute of Technology, 2012)
Impurities are detrimental to silicon-based solar cells. A deeper understanding of their evolution, microscopic distributions, and oxidation states throughout the refining processes may enable the discovery of novel refining ...
SiGe electro-absorption modulators for applications at 1550nm
(Massachusetts Institute of Technology, 2008)
A novel SixGe₁-x, electro-absorption modulator design is experimentally demonstrated. The device is waveguide integrated, butt-coupled into high index contrast Si/SiO2 waveguides. 0.75% Silicon concentration in the alloy ...
