Chen, Chi (2010-10-12)A low temperature scanning tunneling microscope (LTSTM) was built that we could use in an ultra high vacuum (UHV) system. The scanning tunneling microscope (STM) was tested on an existing 3He cryostat and calibrated at ...

Schultz, Isabel (2015-12-02)Mesoscopic materials typically have different properties compared to bulk materials because their dimensions can be smaller than certain characteristic lengths. Transport measurements on mesoscopic-sized disordered materials ...

Tsai, Chen-Fong (2013-05-01)Since the discovery of the high temperature superconductor YBa2Cu3O7-δ (YBCO), with transition temperature (Tc = 77 K), above liquid nitrogen point in 1987 many research projects have been dedicated to enhancing the high ...

Jerebtsov, Sergey N.; Kolomenskii, Alexandre A.; Liu, Haidong; Zhang, Hong; Ye, Zuxin; Luo, Zhiping; Wu, Wenhao; Paulus, Gerhard G.; Schuessler, Hans A. (American Physical Society, 2007)Coherent acoustic oscillations in Bi and Ag nanowire samples were studied with a femtosecond pump-probe technique and detection of the scattered light. The observed optical and acoustic properties reflect the nanostructure ...

Kinaci, Alper (2013-05-02)The ability to manipulate material response to dynamical processes depends on the extent of understanding of transport properties and their variation with chemical and structural features in materials. In this perspective, ...

Sun, Chen (2018-05-16)More than ten years ago, Bose-Einstein condensation (BEC) of magnons (or quantized spin waves) was experimentally observed in yttrium iron garnet (YIG) films at room temperature. Since BEC and superfluidity are closely ...

Liu, Haidong (2010-07-14)This dissertation describes experimental studies of the superconducting proximity effect in single-crystal Pb, Sn, and Zn nanowires of lengths up to 60 um, with both ends of the nanowires in contact with macroscopic ...
-
Okoth, Marion Odul (2011-10-21)This thesis describes the synthesis of a low modulus, thermally conductive thermal interface materials (TIM) using metal decorated nanotubes as fillers. TIMs are very important in electronics because they act as a ...
-
Wei, Zhiyuan (2013-05-01)This dissertation describes experimental studies of the structures and properties, and their correlations in ferromagnetic nanowires and nanotubes fabricated using porous templates. Ferromagnetic Ni and Fe nanowires with ...

Rohe Salomon Da Rosa Rodrigues, Davi (2018-05-22)In this thesis we propose a novel method to study the dynamics of topological magnetic textures. Based on the stability of these objects, scaling and symmetry arguments, we show that, despite the complexity of the micromagnetic ...
