About

Joo Hyun Kim is a leading researcher in the field of two-dimensional (2D) materials and energy harvesting, with a particular focus on phosphorene, or black phosphorus (BP). His major contributions center on the development of flexible and ultra-lightweight energy harvesters, exploiting the unique piezoelectric and semiconducting properties of 2D phosphorene. In his highly cited 2024 work, Kim systematically reviewed the current and futuristic prospects of phosphorene-based devices, highlighting its advantages over graphene—such as a tunable band gap, high on/off current ratio, and biocompatibility. This paper, with 6 citations, has already established a foundation for next-generation wearable and implantable energy technologies. Kim’s research bridges fundamental materials science and practical device engineering, offering pathways to self-powered, flexible electronics. His work is particularly notable for its forward-looking perspective, identifying key challenges and opportunities in scalable synthesis and device integration. By positioning phosphorene as a viable competitor to graphene, Kim has opened new avenues for sustainable, low-power energy solutions, making him a pivotal figure in the advancement of 2D material-based energy harvesting systems.
