Computer aided floating zone growth of Germanium-Silicon crystals in a resistance heated multi-zone furnace
In this work a technologically state-of-the-art growth furnace <br>-- the FMF-module (Floating Zone Furnace with Rotating Magnetic <br>Field) -- is under development for crystal growth experiments on <br>the International Space Station. By using global simulations and <br>the inverse modeling …

A backscattering ion channeling study of the lattice site location of the constituents of two systems
… the extent of antimony segregation to the [111] silicon - silicon dioxide interface was first determined. Channeling scans were made through the [111], [110] and [121] directions of thin silicon crystals with a silicon dioxide layer at the rear surface. By comparing the form of the channeling …

Surface states on the cleaved (III) silicon surface
… vi ty changes resulting when sing.le crystal silicon is cleaved in ultrahigh vacuum have been measured parallel to the cleavage plane over various temperature ranges for gold dope~ and high.resistivity boron doped silicon. The resulting change of conductivity is related to the difference …

Compensation engineering for silicon solar cells
… on the electrical properties of crystalline silicon relevant to the operation of solar cells. We show that the control of the net dopant density, which is essential to the fabrication of high-efficiency solar cells, is very challenging in ingots crystallized with silicon feedstock containing …

The effect of stress on the luminescence spectrum of irradiated silicon
Silicon crystals which have been irradiated with neutrons, high energy electrons, or gamma-rays at room temperature show two strong luminescence bands in the near infrared. Both bands have a sharp zero-phonon line followed by a series of broad phonon assisted peaks. The higher energy band …

Nonlinear Applications using Silicon Nanophotonic Wires
… set of nonlinear-optical applications using silicon nanophotonic "wires" fabricated on a silicon-on-insulator photonic chip. These deeply scaled silicon nanophotonic wires are capable of confining the telecom and mid-infrared (mid-IR) light tightly into an optical-modal area ~ 0.1 𝜇m². The …

Advanced Integration of Devices Enabled by Laser Crystallization of Silicon
… are explored. Thin-film, laser-crystallized silicon transistors are fabricated at low-temperatures and exhibit high mobilities above 400 cm2 2/Vs. Vertical structure diodes built from laser-crystallized silicon outperformed epitaxially-grown diodes of the same geometry. Light emitting diode …
