  2. 36. Magnetic properties of hard-soft amorphous nanolaminates

    Author : Parul Rani; Gabriella Andersson; Petra Jönsson; Kostas Sarakinos; Erik Wahlström; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Amorphous Thin Film; Soft Hard Multilayers; Combinatorial Sputtering; Magnetism; Rigid-Exchange coupling; First-Order Reversal Curve; Fysik; Physics;

    Abstract : Amorphous magnetic thin film heterostructures and multilayers are often used in data storage as well as spintronic devices. Spintronics will help the next generation of nano-electronic devices to increase their memory and processing power and reduce their power consumption. READ MORE

  4. 37. Diamond Devices Based on Valley Polarization

    Author : Nattakarn Suntornwipat; Jan Isberg; Markus Gabrysch; Saman Majdi; Hitoshi Umezawa; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CVD diamond; valleytronics; Negative Differential Mobility; NDM; electron polarization; Time-of-Flight; magnetotransport; carrier transport; drift velocity; valley-transistor; Transferred-Electron Oscillator; TEO; TED; Gunn diode;

    Abstract : Diamond is a wide bandgap semiconductor with extreme properties such as high thermal conductivity, high breakdown field, high carrier mobilities and chemical inertness. These properties together with the possibility to synthesize high purity Single-Crystalline (SC) diamond by Chemical Vapor Deposition (CVD), make it a very interesting material and a candidate for use in power electronics and in hazardous environments.

  7. 40. Spin-dependent recombination in Ga(In)NAs alloys

    Author : Yuttapoom Puttisong; Weimin Chen; Irina Buyanova; Qingxiang Zhao; Linköpings universitet; []
    Keywords : ;

    Abstract : The abilities to control and manipulate electron spin, especially in semiconductors, lead to many interesting proposals for spin-functional devices in future spintronics and quantum information technology. A key requirement for the success of these proposals is that the spin functionality should be operational at room temperature (RT), which remains as a great challenge. READ MORE
