Chemisorption-driven reversible property tuning of nanophase metals and metal oxides Charge- or electrical field-induced tuning of materials properties is usually restricted to non-metals such as semiconductors and piezoelectric ceramics. It could be shown recently that such a tuning can also be achieved with metals when the limits associated with the efficient electronic screening are overcome by a high number of interfaces, i.e., a high surface-to-volume ratio, as available in highly porous nanophase metals. The present work aims at tuning the electrical resistance and the magnetic moment in metals and metal oxides reversibly. One focus is the utilization of reversible surface adsorption/desorption processes which significantly influence the materials properties. |
