Electron-electron interactions can render an otherwise conducting material insulating, with the insulator-metal phase transition in correlated-electron materials being the canonical macroscopic manifestation of the competition between charge-carrier itinerancy and localization. The transition can arise from underlying microscopic interactions among the(More)
Spintronics is a rapidly emerging field of science and technology that will most likely have a significant impact on the future of all aspects of electronics as we continue to move into the 21st century. Conventional electronics are based on the charge of the electron. Attempts to use the other fundamental property of an electron, its spin, have given rise(More)
As classical information technology approaches limits of size and functionality, practitioners are searching for new paradigms for the distribution and processing of information. Our goal in this Introduction is to provide a broad view of the beginning of a new era in information technology, an era of quantum information, where previously underutilized(More)
Recently, with the discovery of multiferroic materials, there has been a great interest in creating logic devices which exploit both magnetic and electric properties of these materials. This paper proposes a reconfigurable array of magnetic automata (RAMA) made of multiferroic nanopillars which can be operated using electric fields. Furthermore, due to the(More)
We investigate the differences in the dynamics of the ultrafast photo-induced metal–insulator transition (MIT) of two VO 2 thin films deposited on different substrates, TiO 2 and Al 2 O 3 , and in particular the temperature dependence of the threshold laser fluence values required to induce various MIT stages in a wide range of sample temperatures 150–320(More)

We study the thermal relaxation dynamics of VO 2 films after the ultrafast photoinduced metal-insulator transition for two VO 2 film samples grown on Al 2 O 3 and TiO 2 substrates. We find two orders of magnitude difference in the recovery time (a few nanoseconds for the VO 2 /Al 2 O 3 sample versus hundreds of nanoseconds for the VO 2 /TiO 2 sample). We(More)
Emerging nanotechnologies have the potential to completely revolutionize the semiconductor industry by providing "more than Moore" capabilities. Instead of trying to compete in areas where conventional CMOS is still dominant, such as digital processing, emerging technologies can provide a perfect complement to CMOS in areas where conventional solutions are(More)
