Overview of Academic Research
Prof. Ma’s research interest is the systematic study on low-dimensional carbon-based spin systems, for resolving the outstanding challenges in developing precise preparation strategies such as on-surface synthesis and tip-assisted manipulation, integrating scanning probe microscopy (SPM) with tip-enhanced Raman spectroscopy (TERS) and electron spin resonance (ESR) techniques, and exploring the potential applications of carbon-based spin qubits in quantum computing and quantum simulation.
His major achievements include:
* Proposed two methods for preparing quasi-freestanding second-layer topological graphene nanoribbons and investigated their topologically-protected end states as well as topologically-localized terminal electronic vibrational excitations.
* Constructed graphene nanoribbons with periodic and specific structures and studied the effects of metal substrate steps and additional atoms on surface reactions.
* Realized the controllable construction of artificial kagome electronic lattices, revealing the existence of topologically protected boundary states.
Research Directions/Fields:
