| Outline of Annual Research Achievements |
This work demonstrates thermal-to-electric energy conversion based on ionic nanofluidic transport in nanochannels inducted by a temperature gradient. Two types of highly periodic and high aspect ratio nanochannels have been fabricated in a silicon (Si) substrate and in an aluminium oxide (Al2O3) membrane. Silicon nanochannels with diameter of 100 nm and height of 300 μm have been produced by metal-assisted chemical etching process (MACE), while nanochannels with the dimensions of the 10 nm and 3 μm respectively, were fabricated in a Al2O3 membrane by the anodic aluminum oxidation (AAO) process. Moreover, a novel approach of thermally nanofluidic energy harvesting was proposed and conducted.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
The concept of thermal-to-electric energy conversion based on ionic nanofluidic transport in nanochannels has been demonstrated.
|
| Strategy for Future Research Activity |
Continue on the optimization of the nanochannel fabrication. Try to make the compact thermoelectric generator module with high performance.
|
| Causes of Carryover |
Due to the COVID 19, some plans have been changed. I would like to perform the optimization of the nanochannel fabrication in next fiscal year.
