My group has a great interest in 2-dimensional materials, in particular, graphene, MoS2, and other atomically thin objects. Graphene, a single sheet of graphite, is only one atom-thick, but can be as large as hundreds of micron across. You may consider graphene as a gigantically conjugated aromatic molecule. Since its first isolation from graphite in 2004, scientists have made various exciting observations (see an essay or a more academic review written by one of the 2010 Nobel laureates in Physics). For example, graphene is tougher than steel and mostly immune to various chemical attacks despite its atomic thickness . While it conducts heat and electricity very well, graphene is highly transparent. Owing to its many attractive properties, graphene holds a great promise in future applications such as electronics, transparent electrodes/display, and smart nanocomposites.
Our immediate goal is to develop various chemical tools to manipulate the properties of graphene and characterize the change by spectroscopic and SPM (scanning probe microscopy) tools. My group is also seeking new properties of other 2-dimensional materials which may lead to exciting applications.
