Investigations on unconventional aspects in the quantum Hall regime of narrow gate defined channels
We report on theoretical and experimental investigations of the integer quantized Hall effect in narrow channels at various mobilities. The Hall bars are defined electrostatically in two-dimensionalExpand

Heavy metals accumulation in freshwater mussels (Lamellidens marginalis) as a biological monitor inhabiting in Dhanmondi Lake, Dhaka, Bangladesh.
The heavy metal concentration (e.g., Mn, Zn, Pb and Ni) were determined in soft tissues and shells of freshwater mussels ( Lamellidens marginalis) at the various sites of Dhanmondi lake, Dhaka,Expand
Distribution of an Ohmic current in the close vicinity of a quantum point contact
We present the essential findings of the screening theory of the integer quantum Hall effect (IQHE) considering a quantum point contact (QPC). Our approach is to solve the Poisson and the SchrodingerExpand

Ja n 20 03 Nonlinear Thomas-Fermi-Poisson theory of screening for a Hall bar under strong magnetic fields
Low-temperature screening properties of the inhomogeneou s two-dimensional electron gas in a Hall bar subjected to a strong perpendicula r magnetic field are explored using a self-consistentExpand
Spatial distribution of the incompressible strips at AB interferometer
Abstract In this work, the edge physics of an Aharonov–Bohm interferometer (ABI) defined on a two dimensional electron gas, subject to strong perpendicular magnetic field B, is investigated. We solveExpand
