I have 10 years of experience in experimental semiconductor physics. My research focuses on quantum phenomena in semiconductor nanostructures and their applications in functional electronic and optoelectronic devices. My current reasearch project is the study of the ferromagnetic semiconductor (GaMn)As and its application in novel nanoscale electronic/optoelectonic devices (O. Makarovsky et. al, Phys. Rev. Lett. 101, 226807 2008 (highlighted by Nature Nanotechnology Dec 2008 and Nature Materials Jan 2009); Phys. Rev. B 77, 026209 2008; Adv. Materials, in press 2010). I am also interested in soft condensed matter electronics (Chemistry of Materials, 22 2675 2010); quantum dots and their applications in single-photon detectors (Phys. Rev. B 79, 193311 2009); hot-carrier electron transport in III-V semiconductors and its applications (Appl. Phys. Lett 96, 052115 2010, Appl. Phys. Lett. 86, 042101 2005); THz phenomena in semiconductors and solid-state THz generators (Phys. Rev. B 72, 033312 2005, Appl. Phys. Lett. 88, 032107 2006). I have played a key role in the development of research facilities at Nottingham, including several cryo-magnetic systems (fields up to 16T, temperatures 0.3K..300K), low noise sub-picoamp DC, RF (GHz and THz) experimental setups, and optical systems for nanoscale spectroscopy and laser annealing. I have also established new international collaborations, which have played a key role in attracting new research funding (Royal Society International Joint Project 2009/R4 ref: JP091217)
