TL;DR: In this paper, self-organized anodic titania nanotube layers were doped with nitrogen successfully using ion implantation, resulting in a N-doped crystalline anatase nanotubite structure with strongly enhanced photocurrent response in both the UV and the visible range.

TL;DR: In this article, N-ion implantation was carried out into amorphous and crystalline (anatase) tubes, which showed a disintegration of the morphological integrity.

TL;DR: In this paper, the authors used 4H-SiC MOSFETs to build NMOS logic gates intended for high temperature operation and characterized the logic gates between 25°C and 500°C.

TL;DR: In this article, the electron mobility in the inversion channel was measured to be correlated with the structural and chemical properties determined by transmission electron microscopy, and interfacial layer formation and carbon distribution across the SiC/SiO2 interface were considered in relation with the measured Hall electron mobility.

TL;DR: The possible contribution of the Poole–Frenkel effect to the conduction mechanism was considered, and it was found that it does not play a dominant role and the possible conduction mechanisms have been identified in the whole measurement range.
