□ Purpose & Contents
2D/ultra-thin materials have huge potential to realize the functional electronic devices on soft platform that overcome the performance of conventional semiconductor devices. However, researches on 2D/ultra-thin materials-based devices has been on the level of studies on device characteristics of a single unit device. Therefore, the goal of this project is to develop devices with which we can make the most of properties of 2D/ultra-thin materials such as high transparency, atomically thin characteristics and outstanding electrical characteristics and to develop technologies to build the integrated circuits on the soft platform beyond a single unit device, and finally to secure the core, original device technologies for the realization of soft electronics system based on our achievement.
In the first phase, researches were carried out to discover the innovative device architectures that can enhance the device performance dramatically by maximizing the unique characteristics of soft low dimensional materials.
In the second phase, researches were carried out to secure basic characteristics of an unit device built by the innovative device architecture and to demonstrate the concept of the integrated circuits that consist of an unit device with the innovative device architecture on the soft/flexible platform.
In the third, final phase, researches focused on the development of integrated circuits with soft innovative devices on the soft/flexible platform in which the performance of soft innovative devices was highly enhanced, based on the results from the first and second phase of project.
