Atomic scale characterization of SiO2/4H-SiC interfaces in MOSFETs devices
(Elsevier, 2015)
The breakthrough of 4H-SiC MOSFETs is stemmed mainly due to the mobility degradation in their channel in spite of the good physical intrinsic material properties. Here, two different n-channel 4H-SiC MOSFETs are characterized ...

A Structural Comparison of Ordered and Non-Ordered Ion Doped Silicate Bioactive Glasses
(MDPI, 2020-02)
One of the key benefits of sol-gel-derived glasses is the presence of a mesoporous structure and the resulting increase in surface area. This enhancement in textural properties has a significant e ect on the physicochemical ...
