Formation of Nanocrystalline Germanium via Oxidation of Si₀.₅₄Ge₀.₄₆ for Memory Device Applications
In this work, we studied the possibility of synthesizing nanocrystalline germanium (Ge) via dry and wet oxidation of both amorphous and polycrystalline Si₀.₅₄Ge₀.₄₆ films. In dry oxidation, Ge was rejected from the growing ...
MOSFET Channel Engineering using Strained Si, SiGe, and Ge Channels
Biaxial tensile strained Si grown on SiGe virtual substrates will be incorporated into future generations of CMOS technology due to the lack of performance increase with scaling. Compressively strained Ge-rich alloys with ...
Charge Storage Mechanism and Size Control of Germanium Nanocrystals in a Tri-layer Insulator Structure of a MIS Memory Device
A method of synthesizing and controlling the size of germanium nanocrystals is developed. A tri-layer metal-insulator-semiconductor (MIS) memory device structure comprising of a thin (~5nm) silicon dioxide (SiO₂) ...
The interfacial reaction of Ni on (100) Si₁âxGex (x=0, 0.25) and (111) Ge
The interfacial reaction of Ni with Si, Si₀.₇₅Ge₀.₂₅, and Ge at 400°C has been investigated. A uniform epitaxial NiSi film was obtained at 400°C for Ni-Silicidation on Si using rapid thermal annealing method. Similarly, ...
SiGe-On-Insulator (SGOI): Two Structures for CMOS Application
Two SiGe-on-insulator (SGOI) structures for CMOS application are presented: surface-channel strained-Si on SGOI (SSOI) and dual-channel SGOI structures. Comparisons between two structures are made from both device performance ...
