Non-equilibrium quantum transport theory for current and noise of single molecules and organized molecular networks
Research Aim
Variations and fluctuations of current is a problem common to nano-structured materials and is a serious problem in the nanoelectronics field. Concerning single-molecule systems, experimental measurement studies on the average value of currents using the break junction technique have been undertaken, and we have been able to explain the results in conjunction with theory. Single-molecule systems are the best systems for researching the problem of ‘fluctuation and variation’ and can advance the collaborative research of theory and experiment. Although we considered attempting a project even more ambitious, including problems such as network storage using the interaction between ‘single-molecule memories’, we plan to make a new theoretical proposal rooted in the fluctuation and variation research results.
Role and Need in the Group
The aim of this research is to explain the nature of fluctuation and variation from the standpoint of material science, and use these findings purposely for creating memory and learning functions in assembled molecular networks. The design guidelines we obtain will lead to success in experimental research areas including synthesis, measurement, and device fabrication.
Research Content
This research group has elucidated problems such as temperature characteristics of currents through a single molecule as well as problems of local heating and heat dissipation by performing quantum conduction calculation that incorporates phonon scattering effects and electron correlation effects. Based on these studies, we will make semiquantitative predictions for specific molecules and materials by performing ab initio calculations as we theoretically elucidate the problem of fluctuation and variation.
