Welcome to the
Atomic Force Microscopy Lab at the
Department of Physics, National Taiwan Normal University.
Our research
interests mainly focus on the physical properties of novel
nano-materials, with a recent emphasis on the frictional and triboelectric properties of 2D materials such as graphene, MoS2, h-BN, and their van der Waals heterostructures. Due to the advancement in nanotechnology,
nano-materials have become promising building blocks for the micro
and nano-electrical-mechanical systems (MEMS
or NEMS), which may revolutionize our life in the near future. For
nanomaterials employed in MEMS or NEMS as moving
components, the deformation, friction,
lubrication and
wear between their surfaces will need to be controlled for
optimal device performance. As a result, a fundamental understanding
about the correlation between nano-mechanical, nano-tribological and
nano-electrical properties of materials at the
nanoscale is highly important for real
applications.
In our lab, we use various state-of-art Atomic Force
Microscopy (AFM)-based techniques to investigate the physical
properties of nano-materials. With force sensitivity as small as
pico-Newton and current sensitivity as tiny as femto-ampere,
we are able to explore the nanoscale world with high precision and
unravel the secrets of
nano-materials.
