RATHNAYAKA, KDD; HENNINGS, BD; Naugle, Donald G. (American Physical Society, 1993)The resistivity of codeposited amorphous Ti1-xAlx films has been measured from 1.5 to 300 K over the composition range 0.4 less-than-or-equal-to x less-than-or-equal-to 0.92, and the Hall coefficient has been measured at ...

WANG, PS; WILLIAMS, JC; RATHNAYAKA, KDD; HENNINGS, BD; Naugle, Donald G.; KAISER, AB. (American Physical Society, 1993)Measurements of the Hall coefficient and resistivity for highly oriented Tl2Ba2CaCu2O8+delta thin films are reported. The temperature dependence of cotTHETA(H), where THETA(H) is the normal-state Hall angle, for a single-phase ...

Chakraborty, S.; Mukherjee, GD; Rathnayaka, KDD; Naugle, Donald G.; Majumdar, AK. (American Physical Society, 2000)Detailed studies of the temperature dependence of the spontaneous magnetization have been made in eight different compositions of gamma-Ni100-x-yFexVy (4 less than or equal to x less than or equal to 17; 2 less than or ...

Ozmetin, Ali E. (2010-07-14)In this work the interactions between neighboring superconducting thin film and ferromagnetic structures, i.e. superconductor-ferromagnet hybrid systems, were studied. A type-II superconducting thin film (Pb82Bi12), was ...
-
Ghassemi, Nader (2020-08-27)Thermoelectric (TE) materials offer interconversion of thermal and electrical energy through the presence of a heat gradient and thus constitute an attractive option for the recovery of waste heat. Low conversion efficiency ...
-
Sirusi Arvij, Ali (2016-10-18)Due to limited sources of fossil fuels worldwide and a large percentage wasted as heat energy, searching for efficient thermoelectric materials to convert heat to electricity has gained a great deal of attention. Most of ...
-
Zheng, Xiang (2012-10-19)Increasing efforts have been put into research about thermoelectric materials for the last few decades, especially recently, faced with the crucial demand for new energy and energy savings. Among the potential candidates ...

Bobrov, NL; Beloborod'ko, SI; Tyutrina, LV; Yanson, IK; Naugle, Donald G.; Rathnayaka, KDD. (American Physical Society, 2005)Point contacts are used to investigate the anisotropy of the superconducting energy gap in LuNi2B2C in the ab plane and along the c axis. It is shown that the experimental curves should be described assuming that the ...
