Because the silicon germanium lattice is larger than the silicon lattice ... and the ends of the dislocations can travel up to the top surface. High densities of dislocations (106 cm2 and greater) ...

Thermal oxide is 'grown' on the surface of silicon wafers by diffusing oxygen atoms into the silicon's crystal lattice. The oxygen atoms break silicon-silicon bonds and form silicon-oxygen bonds ...

Frame (a) shows a schematic of the Nanonet, a lattice structure of Titanium disilicide (TiSi2), coated with silicon (Si) particles to form the active component for Lithium-ion storage. (b) A ...

“If you strain the silicon lattice, then you can improve the electron mobility and performance in your device,” says John Rogers, professor of material science at the University of ...

"This structures the surface and integrates sulfur atoms into the silicon lattice, making the treated material appear black." If manufacturers were to equip their solar cells with this black ...

Mesoporous silicon is crystalline silicon with disordered nanometer-sized pores. The material has a huge internal surface area and ... the possible involvement of lattice vibrations (phonons).

When photons hit the surface of a solar cell ... is made by using precision lasers to "zap" sulfur atoms into the silicon lattice in well-defined patterns. The sulfur lowers the energy gap ...

InGaAs pillar formation begins by etching out the silicon pillars to create a concave bottom surface, slightly wider than the ultimate trench width. Successive depositions of germanium, InP, and ...
