Fullerenes

INTRODUCTION

Fullerenes are unique carbon structures that have great potential for uses in future nanotechnological applications. The simplest fullerene structure is the C₆₀ molecule, which consists of 60 carbon atoms arranged in a spherical shell.

Our research has focused on studying the spatial variation of C₆₀ electronic structure and examining how it is modified by local perturbations. The majority of our work has been conducted on C₆₀ deposited on the Ag(100) surface at 7K.
