Molecular, Quantum Dots and DNA Electronics

Swapan K. Pati

Theoretical Sciences Unit JNCASR, Bangalore 560064, India

In this era of miniaturized devices, we have been trying to develop various quantum theories to describe charge transfer, transport, optical and magnetic phenomena within a unified approach. Towards this end, I shall discuss our efforts to understand Negative differential Resistance/Conductance (NDR/NDC) phenomena in molecules and quantum dots, using both voltage-constraint and current-constraint approaches [1-4]. I shall also discuss a few electronics work that we have carried out on DNA systems [5-7].
