Rigid and flexible optoelectronics devices (OEDs), e.g., solar cells (SCs), LEDs, and photodetectors (PDs) have been widely investigated for potential applications from solar farms to buildings, wearable electronics, and biomedical sensors. The poor heterogeneous interfaces between different layers of OED structures will cause irreversible degradation. In this talk, we will discuss new approaches to enhance the interfaces from electrodes to active layers to achieve high-performance foldable OEDs. While typical transparent electrodes, e.g., indium tin oxide (ITO), are costly and brittle, we developed a new class of foldable transparent electrodes through the unique triple atomic interfacial integrations of composite materials[1], showing superior device stability against mechanical-electrical-moisture operation with a folding radius of 0.75mm. We further improve device performance by several strategies, including sublattice structuring, adhesion enhancement, and strain relaxation of SCs[2-7], synergetic ligand designs of LEDs[8-10], and crystallization enhancement of PDs[11-12]. We demonstrated SCs with 25.8% efficiency and over 2000 hours operational stability[3], pure primary-color ultra-flexible LEDs with prolonged stability[8] and PDs with detectivity surplus III-V semiconductor ones[11].

The advancement of Rydberg atoms in quantum information technology is driving a paradigm shift from classical receivers to Rydberg atomic receivers (RARE). RAREs utilize the electron transition phenomenon of highly-excited atoms to interact with electromagnetic (EM) waves, thereby enabling the detection of wireless signals. Operating at the quantum scale, such new receivers have the potential to breakthrough the sensitivity limit of classical receivers, sparking a revolution in wireless communications. In this talk, I will first introduce the fundamentals of RAREs, covering their definition and properties, the interaction of Rydberg atoms with EM waves, as well as the electromagnetically-induced-transparency based quantum measurement. Then, the pros and cons of of RAREs compared as opposed to classical receivers will be discussed. The second part of this talk will present our latest progress in RARE aided communications and sensing, ranging from MIMO communications, sensing architecture, and integrated communication and sensing. The talk will be concluded with some promising future directions on integration of RARE into modern wireless communication systems.

As we move towards Sixth Generation (6G) wireless networks, the focus shifts from speed and capacity to building intelligent, adaptable, and resilient systems. This talk explores the integration of Artificial Intelligence (AI) into 6G networks, focusing on developing resilient intelligence for dynamic and resource-constrained environments. We present a novel framework that combines reinforcement learning, multi-agent coordination, and reward modeling to tackle challenges in wireless optimization, especially in environments with sparse, noisy, and delayed feedback. Our methods enable continuous adaptation to dynamic changes in traffic, mobility, and energy constraints, enhancing the resilience of 6G systems for critical applications like autonomous transport, industrial IoT, and emergency response. Through practical case studies, we demonstrate how adaptive intelligence can optimize network performance and improve the scalability of future wireless systems, offering insights into the path towards resilient, intelligent 6G networks.
