The Department of Quantum Molecular Devices is engaged in the study for novel devices with quantum effects and molecular functions. This area, which combines nanoelectronics, molecular nanotechnology and bioelectronics, is still in the early stage of development. For this far target, we are
(1) studying surface physics and thin film growth in mesoscopic-scale,
(2) developing processes for fabrication of nanostructures and arrangement of bio-molecules on semiconductor substrates,
(3) investigating the properties of these structures and characteristics as possible devices,
(4) studying DNA computing and
(5) developing bio-sensors and chips and the chemical imaging sensor system.
