Molecular Tuning of the Magnetic Response in Organic Semiconductors [PDF]
The tunability of high-mobility organic semi-conductors (OSCs) holds great promise for molecular spintronics. In this study, we show this extreme variability - and therefore potential tunability - of the molecular gyromagnetic coupling ("g-") tensor with

Chemical, Electronic, and Electrical Properties of Alkylated Ge(111) Surfaces [PDF]
The use of Ge in semiconductor electronics has been constrained by the lack of a simple method of passivating the crystal surface. Toward that end, we have explored the utility of chemically bonded hydrocarbon monolayers.
