Ferromagnetism and Metal-Insulator transition in F-doped LaMnO3
Ekta Yadav, Pramod Ghising, K. P. Rajeev +1
We present our studies on polycrystalline samples of fluorine doped LaMnO3 (LaMnO3-yFy). LaMnO2.5F0.5 exhibits remarkable magnetic and electrical properties. It shows ferromagnetic…
Laser patterned polymer/nanotube composite electrodes for nanowire transistors on flexible substrates
Kiron Prabha Rajeev, Michael Beliatis, Stamatis Georgakopoulos +3
Fabrication techniques such as laser patterning offer excellent potential for low cost and large area device fabrication. Conductive polymers can be used to replace expensive metal…
Electrical analysis of hysteresis in solution processed silicon nanowire field effect transistors
K. Prabha Rajeev, C. Opoku, V. Stolojan +2
Silicon nanowires (Si NW) are ideal candidates for solution processable field effect transistors (FETs). The interface between the nanowire channel and the gate dielectric plays a…
Quantum oscillations with non-zero Berry phase from a complex three dimensional Fermi surface in Bi2Te3
Sourabh Barua, K. P. Rajeev
We performed angle dependent magnetoresistance study of a metallic single crystal sample of Bi2Te3. We find that the magnetoresistance is highly asymmetric in positive and negative…
Experimental evidence for stochastic switching of supercooled phases
Devendra Kumar, K. P. Rajeev, J. A. Alonso +1
First-order phase transition in a highly correlated electron system can manifest as a dynamic phenomenon. The presence of multiple domains of the coexisting phases average out the…
Evidence for topological surface states in metallic single crystals of Bi2Te3
Sourabh Barua, K. P. Rajeev, Anjan K. Gupta
Bi2Te3 is a member of a new class of materials known as topological insulators which are supposed to be insulating in the bulk and conducting on the surface. However experimental v…
