The development of silicon-based electronic devices will arrive at its limitation in the following years and the develop speed has obviously slowed down. In order to manipulate very smaller and faster devices, the semiconductor industries encounter two main difficulties. One is the quantum effect. In the mecroscopic systems, the quantum behaviors of electrons show up and the classical transport theory is no longer applicable. The other is the heat generations observably enlarge if the devices become smaller. Thus, great efforts have been paid to reveal the work principles of mecroscopic devices to depress the power consumption. In recent years, scientists have done some research on transport phenomena in low dimensional mecroscopic systems. Several ideal devices with low heat generation have been designed. Moreover, many fascinating and particular phenomena, entirely the results of quantum effects, have been found in the low dimensional systems. However, in the vast unknown fields, many new physical properties are left to be found and explained. The research fields of T04 group mainly focus on the electronic transport properties in the low-dimensional mecroscopic systems including quantum dot, graphene, topological Insulator, etc. |
