Summary on Grant Application Form
SummaryDescribe the proposed research in about 200 words.Spintronics involves manipulating electron spins for fast electronic devices such as spin transistors and quantum computers. This work has become very important because conventional electronic devices rely on charge transport and as these devices become smaller quantum effects will affect performance. Potential quantum spin devices include single electron spin transistors that rely on spin-dependent tunnelling into a magnetic quantum dot and magnetic field effect transistors that use spin-polarized transport channels. The subject can be considered in terms of characterising single spin systems and many spin systems. In the many spin case, it is necessary to fabricate spin injectors and spin switches to produce and control spinpolarized currents, while in the single spin studies it is necessary to characterise structures which will detect and manipulate single-spin states for quantum computer memory devices. Although many aspects of spintronics have been addressed over the years there is still no established materials route that has come to the forefront. We intend to use the Heriot-Watt expertise in II-VI growth to explore spin injection devices based on the remarkable spin-polarisations possible in these materials and investigate spin injection into magnetic quantum dots by established nano-optic techniques. We will also address the interesting problem of whether room temperature ferromagnetism is possible in II-VI semiconductors by collaborating with Prof, J-P Faurie's Group at the CHREA-CNRS laboratory in Valbonne, France which will supply us with ZnMnO and ZnCoO layers.
