Condensed Matter Spectroscopy Laboratory (CMSL) consists of researchers working at the Department of Physics, Ewha Womans University in Seoul, Korea.
CMSL's main interest lies in studying various condensed matter systems by using optical spectroscopic techniques such as inelastic light scattering (a.k.a. Raman scattering), photoluminescence, absorption, and spectroscopic ellipsometry.
Current interests, as of May 2025, include:
- Entropy-stabilized oxide materials
- Semiconductor heterostructures
- Hybrid materials exhibiting phase transitions
1. Properties of complex materials
- Relations among optical, structural, and electronic characteristics in materials
- Effects of internal degrees of freedom esp. in hybrid organic-inorganic perovskite materials
- Spectroscopic studies of defects
- Spectroscopic studies of entropy-stabilized oxides
- Finding optimized growth conditions of materials for device applications
- Mechanism(s) of complex phase transitions
2. Spectroscopic studies of low dimensional materials
- Emergent phenomena due to light-matter interaction in low dimensional materials
- Optical properties and their characteristics
- Manifestation of different excitons
- Charge transfer effects and their results
- Basic properties (growth direction, stoichiometry, structural information, etc.)
3. Basics of Raman scattering
- Raman manifestation of elementary excitations inside materials
- Application of Raman scattering spectrocopy to diverse areas
- Resonant Raman scattering
- Enhancement mechanism(s) of SERS (surface enhanced Raman scattering)
