Abstract: In this project, we propose to design, fabricate, characterize, and analyze new semiconductor hybrid materials. With the discovered new physical phenomena, we aim to create sustainable and intelligent devices with high performance. The main topics of this proposal will be focused on: 1.Electrically driven cavity-free lasers and Anderson localization The requirements to achieve a cavity-free laser are much less than those of conventional lasers. We therefore can fabricate cavity-free lasers with different kinds of functionalities that are not achievable by conventional lasers, such as stretchability, dissolvability, attachable on arbitrary surfaces. In this proposal, in addition to develop different cavity-free laser systems with unique features, including magnetically controllable random laser and acoustic wave tunable random laser, we will develop a new mechanism to develop electrically driven cavity-free laser, which is very rare in all previous reports and important for practical application. Furthermore, we will study the relationship between three dimensional random laser systems and Anderson location, which is still an unresolved issue in this field. 2.Magnetoelectronic skin: an additional perception of artificial intelligence Unlike human beings, many animals in this planet are very sensitive to magnetic field, which enables them to exhibit many unique features beyond the capabilities of our imagination. If the future developed artificial intelligence can be implemented with magnetoelectronic skin, it will process multifunctionalities exceeding human beings. In this proposal, we will develop magnetoelectronic skin having high performance optoelectronic properties with flexibility and stretchability. Since the related research is just in its infancy stage, we believe that with our experience we should be able to discover several interesting phenomena and develop unique magneto-optoelectronic devices. 3.Development of sustainable devices With the rapid progress of science and technology, it revolutionizes our daily life and culture. Even through this trend can improve the quality of life greatly, it generates a mass amount of electronic waste, which can damage our living earth. To circumvent this critical issue, in this proposal we intend to develop eco-friendly devices with the capabilities of dissolvability, recyclability, and self-healing. 4.Vertical stacking of different dimensional semiconductor materials: physics and devices With different dimensionality, semiconductors can exhibit different behaviors. Based upon a suitable design, one can vertically stack different semiconductor materials with different dimensionality and create novel phenomena and optoelectronic devices. In this proposal, in particular, we will focus on the development of semiconductor nanocomposites with multifunctionalities, such as having dual functions of emitting and detecting electromagnetic waves, encoding information with light emission capability, flexible and stretchable devices, and deep UV optoelectronic devices. 5.Optical and electric memories with multifunctionalities Optical and electric memories play a very important role in information technology. However, up to now, they were fabricated and implemented as two different components, which are bulky and only have a limited application. In this proposal, we will develop novel devices that process multifunctionalities, including optical encoding, electrical encoding, optical reading, and electrical reading. The developed device will have a great impact in the future information technology.
