Ph.D Thesis TitleMagnetotransport properties of AlGaAs/GaAs single and bilayer system with InAs quantum dots.Abstract of my thesisThe basic objective of my work is to study the electron transport in heterostructures inwhich the electrons in the quantum well and the quantum dots (QDs) are strongly coupled. In thisstudy we investigated (a) Coulombic interaction between the electrons in QDs and twodimensional electron gas (2DEG), (b) dynamics of electron tunneling between QD and 2DEG,and (c) charge trapping mechanism in embedded QDs. We also studied the interaction betweenthe edge states of two nearby 2DEG with different starting disorders. One focus was also on thecrossover from the insulating to quantum Hall liquid phase which develops from being apractical problem, i.e. switching the device from the ON to the OFF state, towards becoming anintriguing scientific problem.Career ObjectiveTo achieve core competency in chosen fieldResearch ExperienceMy field of expertise is low temperature magnetotransport studies of 2D electron gas inGaAs/AlGaAs heterostructure embedded with InAs quantum dots. After receiving my doctorate,I am working on fabricating graphene field effect devices. My task is to make graphene viachemical route i.e by chemical reduction of graphite oxide. I can personally handle liquid Heliumcryostat fitted with superconducting magnets. Currently I am actively involved in the installationof Helium-3 dilution refrigerator (Kelvinox) in our laboratory. This Helium-3 dilution fridge willbe combined with AFM-STM set-up with the objective to perform local spectroscopy studies ofphase-coherent quantum structures at low temperature (20 mK) and high magnetic fields. I haveexperience in operating FE-SEM, XRD and closed cycle cryostats as well.2
