Colloidal Nanocrytals for Electronics, Optoelectronics, and Energy Applications

The Materials Chemistry Lab, led by Professor Taejong Paik in the School of Integrative Engineering at Chung-Ang University, focuses on the design and synthesis of novel colloidal nanocrystals and their integration into next-generation electronic, optoelectronic, and energy systems. Our research aims to develop new classes of semiconducting nanomaterials through rational synthetic design, with precise control over composition, morphology, and phase.

Key research directions include:

• Designing synthetic strategies for novel colloidal nanocrystals with tailored optical and electronic functionalities

• Developing semiconducting and hybrid nanomaterials, including metal oxides, halide perovskites, and chalcohalides

• Exploring electronic and optoelectronic applications, such as transistors, photodetectors, light-emitting devices, and photoelectrochemical systems for solar-driven hydrogen production

• Creating smart and responsive materials for energy-efficient technologies, including metal oxide and thermochromic materials for passive radiative cooling and solar modulation
  
  

Our approach combines advanced wet-chemical synthesis, nanostructure engineering, and multimodal characterization to establish structure–property relationships and enable their translation into functional devices. Through this, we aim to contribute to sustainable solutions for clean energy and next-generation information technologies.

We welcome interdisciplinary collaboration and are always looking for motivated students and researchers passionate about functional nanocrystals and their applications in energy and electronics.
