Research Abstract |
Using the conventional semiconductor nanofabcation techniques, we have developed techniques to fabricate simple integrated quantum dot devices. With the aligned growth technique and the print-transfer technique, we have fabricated capacitively coupled double quantum dots that demonstrate the charge detection. On the other hand, we have developed techniques to form carbon nanotube/molecule heterostructures. As examples, we have fabricated quantum dots which showed coherent interaction with light. Another example is an individual ring with both nanotube ends bonded chemically, and its electronic structures are studied by the scanning tunneling spectroscopy.
