One of the latest advancements in the field of
two-dimensional semiconducting materials centers on molybdenum
disulfide (MoS), which is being explored for use in
Recently, a team co-led by Qiaoqiang Gan, assistant professor of
electrical engineering, placed a single layer of MoS molecules on
top of a photonic structure called an optical nanocavity made of
aluminum oxide and aluminum.
The results, described in the paper “MoS monolayers on
nanocavities: enhancement in light-matter interaction” and
published in the journal 2D Materials, are promising.
“The nanocavity we have developed has many potential
applications,” said Gan. “It could potentially be used
to create more efficient and ﬂexible solar panels, and
faster photodetectors for video cameras and other devices. It may
even be used to produce hydrogen fuel through water splitting more
