Developing nano-scale fabrication to realize the next generation electron devices, and subsequently characterize their electrical properties.
π-electronics group in MANA investigates using the unique self-assembling nature of -electron materials to control of electrical transport for next generation electronics. π-electron materials to control of electrical transport for next generation electronics. π-electron materials are principally composed of carbon atoms that have conjugated, planar π-bonds. These planes self-assemble by stacking to form a unit lattice or crystal.

Electrical transport in these materials is different from that of classical semiconductors in which electrons or holes are induced by doping to conduct current. Conversely, charge from electrodes is injected into π-electron materials by tuning the difference between the work function of the electrode metal and the energy level of these materials.
Some of these carbon-based π-electron materials can also be coated and patterned onto a plastic substrate as transistors (organic transistors); others can form one-atom thick devices (graphene-based devices) which possess significantly higher electron mobility than that of silicon devices.
However, in practical devices, it does not show ideal phenomena. We challenge to reveal these unpredicted phenomena from micro-/nano-fabrication technique, physical properties of the materials or by a careful control of material structure.
