Sensing the THz Field by an Array of Carbon Nanotube Quantum Wells
Abstract
The efforts during the project period had been directed to solving of several fundamental problems which are critical to a successful invention of new THz nano-sensors and spectral analyzers. The basic problems which we had solved theoretically within the project were as follows. (i) The THz field induces the electron transport on nanoscale which requires new approaches. (ii) The elementary excitations in the CNT are not mere electrons and holes as it is in regular semiconductors. They are rather quasiparticles which are characterized by chirality and pseudospins. (iii) The electron transport occurs through numerous potential barriers of arbitrary transparency along and in-perpendicular to the CNT axis. Therefore its adequate description requires special methods. (iv) The THz field which acts on the CNT quantum well might have an arbitrary intensity. The aforementioned problems (i)-(iv) had to be accomplished theoretically which was the purpose of the theoretical research within the project. Another purpose of the theory was to interpreting of the experimental data obtained by the partner Georgetown group (Prof. P. Barbara).
