In this article, we report the temperature-dependent transistor characteristic of Epi-Gd2O3/AlGaN/GaN metal oxide semiconductor high electron mobility transistor (MOSHEMT) and compare its properties with that of AlGaN/GaN metal-Schottky high electron

The influence of growth conditions on the layer orientation, domain structure and crystal structure of gadolinium oxide (Gd2O3) on silicon (001) has been investigated. Gd2O3 was grown at low (250°C) and high (850°C) temperatures with different oxyg

The effects of nitrogen incorporation by high-dose ion implantation in epitaxial gadolinium oxide (Gd2O3) films on Si (111) followed by annealing have been investigated. The nitrogen content in the oxide layer was changed by altering the implantation

We report on the growth of non-cubic gadolinium oxide on a silicon substrate using molecular beam epitaxy. Structural investigations with X-ray diffraction show that the structure of the oxide differs from the expected cubic structure. Possible struc

For boron implants made with ion implanters designed for PV applications, a variety of ion species BF x ( x =0.2) is implanted, while BF 2 accounts for the lions share. We investigate the impact of the BF 2 implantation dose and the annealing conditi
