| Research Abstract |
In this study, a concept of "nano-heater" has been studied using relaxation of localized surface plasmons on metal nanostructures, which is expected to realize local heating of a specific spatial region at the nanoscale.
To demonstrate the concept, two different model reactions have been examined: DNA dehybridization at 100 degree C in colloidal solution and Si-C bond formation at 200 degree C on H-terminated Si(111) surface. Moreover, plasmon resonance features of transition metal nanostructures have been studied to achieve higher temperature local heating.
The results clearly show that the "nano-heater" is applicable for nano-fabrication using heat-reactions and noble chemical synthetic methods.
