Hybrid optical measurement technique for detection of defects in epitaxially grown 4H-SiC layers [PDF]

open access: yesEPJ Web of Conferences, 2022
Recent developments in power electronics require the use of new wide bandgap compound semiconductor. We demonstrate the use of the ellipsometry and white light interference microscopy to detect defects in epitaxially grown SiC layers on SiC substrates ...

Application of imaging ellipsometry and white light interference microscopy for detection of defects in epitaxially grown 4H–SiC layers

open access: yesJournal of the European Optical Society-Rapid Publications, 2023
Critical defects, also known as device killers, in wide bandgap semiconductors significantly affect the performance of power electronic devices. We used the methods imaging ellipsometry (IE) and white light interference microscopy (WLIM) in a hybrid ...

The Kenya rift revisited: insights into lithospheric strength through data-driven 3-D gravity and thermal modelling [PDF]

open access: yesSolid Earth, 2017
We present three-dimensional (3-D) models that describe the present-day thermal and rheological state of the lithosphere of the greater Kenya rift region aiming at a better understanding of the rift evolution, with a particular focus on plume–lithosphere
