1. 1. Spin generation and detection in low-dimensional semiconductors

   Författare :Yuqing Huang; Weimin Chen; Irina A Buyanova; Sergey Ganichev; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Semiconductor spintronics and opto-spintronics have intrigued intense attention as they promise great advance of contemporary semiconductor information technology with integrated spin functionalities. Over the last few decades, the development of growth techniques and discovery of topological band structures have led to the explosion of a wide range of low-dimensional semiconductor materials, many of which have superior properties compared to their bulk ancestors.

3. 2. Magnetooptical properties of dilute nitride nanowires

   Författare :Mattias Jansson; Irina A Buyanova; Weimin Chen; Jan Eric Stehr; Hannah Joyce; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Nanostructured III-V semiconductors have emerged as one of the most promising materials systems for future optoelectronic applications. While planar III-V compounds are already at the center of the ongoing lighting revolution, where older light sources are replaced by modern white light LEDs, fabricating such materials in novel architectures, such as nanowires and quantum dots, creates new possibilities for optoelectronic applications.

5. 4. Spin-dependent recombination in Ga(In)NAs alloys

   Författare :Yuttapoom Puttisong; Weimin Chen; Irina Buyanova; Qingxiang Zhao; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : 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. LÄS MER

7. 5. Spin Properties in InAs/GaAs Quantum Dot based Nanostructures

   Författare :Jan Beyer; Weimin Chen; Irina Buyanova; Hongqi Xu; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : Semiconductor quantum dots (QDs) are a promising building block of future spin-functional devices for applications in spintronics and quantum information processing. Essential to the realization of such devices is our ability to create a desired spin orientation of charge carriers (electrons and holes), typically via injection of spin polarized carriers from other parts of the QD structures.
