Atomic energies are used to describe local stability in eight low-lying water hexamers: prism, cage, boat 1, boat 2, bag, chair, book 1, and book 2. The energies are evaluated using the quantum theory of atoms in molecules (QTAIM) at MP2/aug-cc-pVTZ geometries. It is found that the simple, stabilizing cooperativity observed in linear hydrogen-bonded water(More)
In this paper we demonstrate the performance and reliability of 1200V SiC DMOSFETs manufactured in a high volume 150mm Si CMOS foundry. These DMOSFETs exhibit less than a 10% shift in threshold voltage and practically no change in breakdown characteristics after high temperature stress tests at 175°C. The performance of very large area 6.30 ×(More)
