Charge Density Waves (CDWs) in Transition Metal Dichalcogenides (TMDs)
• Modulation of charge density waves in TMDs (e.g. VSe₂, VTe₂)
• Control of CDW phases via intercalation, and local excitation
Molecules on surfaces
• Effect of interfacial interactions on electronic properties of adsorbed molecules
• Manipulation of molecular conformations
• Interaction with 2D materials: self-organization, electronic coupling, role of defects
