CVD growth of high speed SiGe HBTs using SiH4

Journal of Telecommunications and Information Technology, 2000
The growth of high frequency HBT structures using silane-based epitaxy has been studied. The integrity of SiGe layers in the base and the control of the collector profile using As- or P-doping grown at 650 oC have been investigated.

Influence of Silane Pretreatment and Warm Air-Drying on Long-Term Composite Adaptation to Lithium Disilicate Ceramic

Crystals, 2021
Background: Repair bonding to lithium disilicate ceramic (LDS) remains an issue. This study examined whether the adaptation of a resin composite to LDS can be improved by a silane pretreatment and warm air-drying. Methods: LDS blocks (IPS e.max CAD) with

A study of nano-particle based silane consolidants for Globigerina limestone [PDF]

, 2013
This STEPS funded study focuses on the application of hybrid and nanoparticle loaded hybrid silane consolidants for the treatment of 'Franka' type Globigerina Limestone. Consolidants act by gluing the deteriorated stone material to the underlying healthy

High-Pressure Phases of Silane [PDF]

Physical Review Letters, 2006
It has been suggested that hydrogen may metallise at lower pressures if it is ``precompressed''. Here we introduce a search strategy for predicting high-pressure structures and apply it to silane using first-principles electronic structure computations.
