Summary on Grant Application Form

The proposed programme involves extensive FS materials and device development and fundamental experimental and theoretical studies of their magnetic, magnetotransport and magneto-optical properties. The programme should significantly advance our understanding of ferromagnetic semiconductors and spintronic devices. The structure of the proposed programme is motivated by the key requirements of functional spintronics. These are the development of a clear understanding of spintronic devices and the development of FS materials with Tc significantly above room temperature.(In,Ga,AI)MnAs will play a central role in this programme. We will carry out a series of interrelated growth, experimental and theoretical studies to improve our understanding of the ferromagnetism in this system and to improve upon our recent record Tc values. This system will also be used in extensive studies on magneto-transport and magneto-optics in FS epilayers, heterostructures and spintronic devices. We will also systematically investigate nitride FS materials, in which room temperature ferromagnetism has been observed or predicted, to establish if they are viable materials for room temperature spintronics. A preliminary study of the growth of FS Quantum dots will also be carried out.The fundamental physics and device aspects of the programme involve extensive experimental and theoretical investigations of magneto-transport and magneto-optical properties of ferromagnetic materials and spintronics devices. We will study in detail the magnetotransport properties of (In,Ga,AI)MnAs and make quantitative comparisons between the experimental and theoretical results obtained. We will carry out extensive investigations of FS tunnelling structures including TMR and Resonant TMR devices. The magneto-optics of FS based PIPIN and resonant tunnelling LEDs will also be investigated. Based on our recent successes and our track record on materials development and heterostructure devices, we believe that the proposed programme will enable the UK to establish a leading role in this field.This programme will also make FS materials and devices available to external academic and industrial research groups in the UK.
