We develop scanning tunneling microscopy (STM), non-contact atomic force microscopy (AFM) and tip-enhance Raman spectroscopy (TERS) to investige and control the electronic, geometric and vibrational properties of single molecules.

Based on rationally designed organic precursor molecules, graphene nanoribbons (GNRs) and polymers with atomic precision can be synthesized from on-surface reactions. The structural, electronic, spintronic and vibrational properties will be investigated by STM, AFM, TERS, and the state-of-the-art electron spin resonance (ESR)-STM.

We use molecular beam epitaxy (MBE), pulse laser deposition (PLD), chemical vapor deposition (CVD) methods to epitaxially grow low-dimensional materials of stanene (Sn), Bismuth (Bi) and graphene, and investigate their quantum properties by using STM and ARPES.

The transition metal oxides hold versatile physical and chemical properties from catalysis to superconductivity, which have attracted considerable research interests for many years. However, the geometric and eletronic properties of oxides are still elusive.
