More efficient electronic devices and energy harvesting materials. With the upcoming 4th industrial revolution, internet of things IOT is one of the hottest topic of scientific community. With IOT, the total quantity of information to be produced and stored exponentially increases, and accordingly number of electronic devices also dramatically increases. With such a trend, energy consumed by electronic devices is becoming a serious issue of modern society. To resolve the aforementioned energy issue of electronic devices, we can have two main strategies. First, more energy efficient devices are highly required. To date, scaling down of electronic devices has improves the performance of the electronic devices. However, now the device size is even smaller than 20 nm, and scaling down of the electronic devices cannot guarantee improving performance of nanoscale devices. Especially, the energy efficiency is one of the most serious problems since the off-state energy consumption rapidly increases with such small sizes. Second, nanoscale energy harvesting device can be the other solution for resolving the energy issue. For this purpose, many research groups intensively studied numerous methodology to harvest electrical energy. From materials point of view, coupling of different material properties is highly promising. Therefore, our group's goal is to study materials for more energy-efficient electronic devices and energy harvesting devices to resolve energy issues of the state-of-the-art electronic devices.
