Comprehensive Study of Signature of Defects in Raman and Photoluminescence response of Transition Metal Dichalcogenides

Master projects/internships - Leuven | More than two weeks ago

Spectroscopy, Transition metal dichalcogenides (TMDCs), Metrology, Raman, Photoluminescence

Recent developments in the application of transition metal dichalcogenides (TMDCs) in electronics suggest a significant role of these materials in future transistor devices. This creates a demand for metrology techniques to understand the unique physics and chemistry of the material and assess the quality. Raman and photoluminescence spectroscopy are powerful nondestructive metrology techniques capable of extracting material properties. The applicability of these techniques to study TMDCs is already well established and their capabilities demonstrated in many previous studies. Despite the sensitivity of these techniques to the presence of defectivity in the 2D layer, unique signatures of specific defects like metal or chalcogen vacancies or di-vacancies remain hard to distinguish from the optical response of the material. The goal of this project is to use correlative studies with electron microscopy to pinpoint the signature of different defects in the optical response of TMDC layers. The student will be trained to use a micro-Raman spectrometer to carry out the measurements and characterize TMDC samples, including data processing and interpretation. This position is defined in the materials and component analysis (MCA) department.
