Metal-insulator transition in correlated two-dimensional systems with disorder
Dragana Popović
Experimental evidence for the possible universality classes of the metal-insulator transition (MIT) in two dimensions (2D) is discussed. Sufficiently strong disorder, in particular…
Conductance noise in an out-of-equilibrium two-dimensional electron system
Ping V. Lin, Xiaoyan Shi, J. Jaroszynski +1
A study of the conductance noise in a two-dimensional electron system (2DES) in Si at low temperatures (T) reveals the onset of large, non-Gaussian noise after cooling from an equi…
History dependent magnetoresistance in lightly doped La_{2-x}Sr_{x}CuO_{4} thin films
Xiaoyan Shi, Dragana Popović, C. Panagopoulos +3
The in-plane magnetoresistance (MR) in atomically smooth La_{2-x}Sr_{x}CuO_{4} thin films grown by molecular-beam-epitaxy was measured in magnetic fields B up to 9 T over a wide ra…
Memory Effects in the Charge Response of Lightly Doped La_{2-x}Sr_{x}CuO_{4}
I. Raičević, Dragana Popović, C. Panagopoulos +1
The in-plane magnetoresistance (MR) of a single crystal La_{1.97}Sr_{0.03}CuO_{4} has been studied at low temperatures T using several experimental protocols. At T well below the s…
Non-Gaussian Noise in the In-Plane Transport of Lightly Doped La_{2-x}Sr_{x}CuO_4: Evidence for a Collective State of Charge Clusters
I. Raičević, Dragana Popović, C. Panagopoulos +1
A study of the in-plane resistance noise on a high quality single crystal of La_{1.97}Sr_{0.03}CuO_{4} deep inside the spin-glass phase reveals the onset of non-Gaussianity and the…
Absence of Localization in Certain Field Effect Transistors
S Washburn, D Popovic, KP Li +1
We review some experimental and theoretical results on the metal-to-insulator transition (MIT) observed at zero magnetic field (B=0) in several two-dimensional electron systems (2D…
