Current Research Interests
We study the physics of the
submicron (or nano) world of semiconductors. In this regime the electrons
behave like waves and interfere. Interference effects affect strongly the
behavior of nano devices. The world of nano devices is the world of low
dimensional structures. Hence, we specialize in reducing the size of
electronic devices and lowering their dimensions to 2, 1 and 0. In such
nanostructures we study the phase electrons gain as they move through complex
structures and the mechanisms that lead to phase smearing and 'decoherence'
of electrons (leading to'particle-like' behavior).
We also study the time sequence of electron propagation, namely, whether
their motion is random or ordered. Such temporal measurements leads to new
information of the system not apparently conductance measurements, moreover,
it allows one to measure the charge of the particles that carry the current.
Such measurements allowed recently to measure the charge of the
quasi-particle in the Fractional Quantum Hall regime. Charge of e/3 and
e/5 were measured. Such effects might dominate the behavior of future
electronic devices as their dimensions reach the deep submicron regime.
