Incorporating the state-of-the-art instrumentation we are able to understand and harness unexplored fundamental interactions at atomic and molecular level by unconventional approaches. Main project is three folds: 1. We will design novel nanocomposites based on compound semiconductors and investigate their unique properties. Due to the inherent nature of a large interface area of nanocomposite systems, there exists a strong coupling strength, which can generate new physical properties in our designed systems. Here, the main topics will be focused on (1) Spin generation and detection, (2) Flexible and stretchable devices and their physical properties, (3) Bio-inspired optoelectronic devices and their physical properties, (4) Novel physical phenomena based on semiconductor nanocomposites, (5) Highly efficient solar cells. They will be far-reaching in future applications of green devices. 2. We will develop novel synthetic strategies for well-defined polythiophene-based polymers, and aim for investigating the formation mechanism of macroscopically oriented polymer films assembled from the electroactive polythiophenes as well as their anisotropic electronic and photophysical properties. Using the state-of-the-art accessory provided by Center of Synchrotron Radiation, we will systematically analyze the phase-separation behaviors and structures of a series of polymer/fullerene blends to maximize the conditions for solar devices in terms of high efficiency and high stability. 3. We then aim at understanding and harnessing the unexplored matter interactions at atomic and molecular level by unconventional approaches. To achieve this goal, an in-situ spatially/temporally coherent analysis platform equipped with multi-probes will be developed, in which SPM system will be coupled with a RAMAN system to achieve a structural investigation within atomic and molecular scale, and this multi-probes platform can perform multifunctional probes to a targeted single reaction. This approach is unprecedented.複合奈米半導體材料耦合機制生物啟發光電元件綠能元件共軛高分子分子排列hybrid semiconductor nanomaterialscoupling mechanism,bio-inspired optoelectronic devicesgreen devicesconjugated polymermolecular ordering
