Characterization of Complex Stacking of Semiconductors Through Near Field Imaging and Spectroscopy. [PDF]

Adv Mater
SNOM imaging and spectroscopy on a mechanically cleaved facet is used to characterize the different layers of complex epitaxial heterostructures composed of a type II superlattice and highly doped semiconductors. Both the geometrical parameters of the stack and the optical properties of the individual layers and of the interfaces are retrieved, as well

Chemical Mechanical Polishing of GaSb Wafers for Significantly Improved Surface Quality

Frontiers in Materials, 2021
Gallium antimonide (GaSb) is considered an ideal substrate for heterostructure growth via molecular beam epitaxy. A significant aspect that inhibits the widespread application of infrared plane-array detector growth on GaSb is the starting substrate ...

High Hole Mobility and Low Leakage Thin-Body (In)GaSb p-MOSFETs Grown on High-Bandgap AlGaSb

IEEE Journal of the Electron Devices Society, 2021
In this study, we demonstrated low leakage current and high mobility thin body (In)GaSb p-FETs. Through the optimization of the V/III ratio during the epitaxial growth, we achieved a highly insulating bottom Al0.95Ga0.05Sb barrier, which eliminates the ...
