Research Interest

The focus of this lab is to study strongly correlated electron systems in low dimensions

 
 

THIN FILM HETEROSTRUCTURES AND INTERFACES

  • Deposition Techniques – Pulse laser ablation, magnetron sputtering, e-beam evaporation, vapour phase epitaxy

  • Materials – Doped metal oxides of perovskite, Ruddelson – Popper and pyrochlore family, elemental oxides, transition metal nitrides, full Heusler alloys and ferromagnetic metals and alloys.

 
 
 

NANOSCALE SUPERCONDUCTIVITY

  • Superconductor – ferromagnet junctions – proximity effect, re-entrant behaviour, coexistence and competition.

  • Superconductor – Insulator (normal metal) quantum phase transition in two –dimensional electron gases, superconductor – insulator transition in proximity coupled systems, vortex state in spin ice structures.

   
 
 

NANOSCALE MAGNETISM

  • In-plane and out of plane magnetic anisotropy patterned films and multilayers, Chiral magnetic order and non-trivial spin textures.

  • Spin transport through non-magnetic channels, inverse spin Hall Effect in insulating ferrimagnet – 5d metal junctions.

   
 
 

LOW TEMPERATURE QUANTUM TRANSPORT IN HETEROSTRUCTURE

  • Rashba spin – orbit interaction driven transport at low temperatures, weak localization and antilocalization in 2D diffusive metals, Kondo problem in 2D, magneto-thermopower in 2D systems.

 

   
 
 

PHOTO-EFFECTS

  • Photoconductivity and photoluminescence in oxide based two-dimensional electron gas systems
