With the upcoming 4th industrial revolution, IoT and big data are the hottest topics of scientific community. As a result, the total quantity of information to be processed 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. Second, nanoscale energy harvesting device can be the other solution for resolving the energy issue. 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.
