Many of the properties of Si-based ceramics, including their structural behavior, are strongly influenced by their micro/nanostructure and by the microscopic residual stress fields piled up during processing and/or usage. The electron beam, used as a sharp and reliable probe for high-resolution hodoluminescence (CL) assessments, can routinely provide a suitable tool for assessing both the

Polycrystalline panels are typically more affordable than monocrystalline panels, but they are not as efficient at absorbing sunlight and converting it to usable electricity. 0 Instead of one large silicon crystal, multiple smaller crystals make up polycrystalline panels.
Baffle wafers of polycrystalline silicon are placed in non-production slots of a support tower for thermal processing monocrystalline silicon wafers. The polycrystalline silicon is preferably randomly oriented Czochralski polysilicon grown using a randomly oriented seed, for example, CVD grown silicon. An all-silicon hot zone of a thermal furnace may include a silicon support tower placed

Polycrystalline silicon has played an important role in integrated-circuit technology for two decades. It was first used in self-aligned, silicon-gate, MOS ICs to reduce capacitance and improve circuit speed. In addition to this dominant use, polysilicon is now also included in virtually all modern bipolar ICs, where it improves the basic

Polycarbosilane (PCS) thin films were deposited on silicon (and other) substrates and heat treated under vacuum (∼10 ‐ ‐6>torr)at temperatures in the range of 200°–1200°C. At temperatures in the range of 1000°–1200°C, the initially amorphous PCS films transformed to polycrystalline ß‐silicon carbide (ß‐SiC).
