We use an array of gate electrodes to control the electrostatic profile in a layer of self-assembled InAs quantum dots. In combination with magnetotunneling spectroscopy, this allows us to identify and measure the energy levels and wave functions associated with the ground and excited state of an individual quantum dot. © 2001 American Institute of Physics.

    We conducted spin-dependent tunneling spectroscopy measurements in Fe/ZnSe/Ga1-xMnxAs magnetic tunnel diodes that had a metal-insulator-semiconductor structure. The tunneling magnetoresistance signal in differential conductance spectra (dI/dV-V) was found to disappear for bias voltages (V)...

    By single-electron tunneling spectroscopy we investigate the difference in spin splitting of single-electron resonances in a double-barrier structure subjected to a magnetic field perpendicular (Δ⊥) and parallel (Δ∥) to the plane of quantum well. The observed anisotropy of spin...

    In silicon nanoscale transistors, dopant (impurity) atoms can significantly affect transport characteristics, in particular at low temperatures. Coupling of neighboring dopants in such devices is essential in defining the properties for transport. In this work, we briefly present a comparison of...

    We experimentally studied the photocurrent of AlAs/GaAs/AlAs double barrier resonant tunneling diode (RTD), which is composed of an InAs layer of self-assembled quantum-dots on top of AlAs barrier layer. It is found that the charging InAs quantum dots can effectively modulate the carrier...

    The conductance of a pair of quantum dots, coupled through a tunnel barrier and connected to two external leads, exceeds the conductance of the tunnel barrier alone (tunneling enhancement effect) if the device is symmetrical, while it strongly decreases if the symmetry is destroyed. This device...
