What do I believe:
Always start with the end in mind, creative thinking and hard working.
Research interests:
Something potentially useful, something practically essential, something
intellectually challenge.
What am I doing:
Dip pen nanolithography, Nanodevices
and miniaturized device (sensor and beyond). If you have further
interests, I can tell you more on these and others.
How can I do:
(1) Synthesis functional building blocks, (2) Device integration
by lithographic techniques, (3) Structural characterization by scanning
probe microscopes and electronic microscopes, (4) Performance evaluation
by electric or optical measurements.
One sentence on my ground project (dip pen nanolithography):
According to the
second law of thermodynamic, it is easier to make things dirty
than to make them clean, what I am doing is to make a surface dirty
on specific position but at nanometer scale.
Research background:
My research involves manipulating molecular building block using
various lithographic method for constructing miniaturized or nano-devices.
Advanced microscope techniques are frequently used for the structural
characterization and electric or optical measurements are used to
test the performances of such devices.

Project Q & A:
Q: What is nano-lithography?
A: The lithography stands for stone drawing in Greek; Nanolithography
means the drawing anything on nanometer scale, but not necessarily
on stone (silicon oxide).
Q: What is the relationship between nanopatterning and nanolithography?
A: Rigorously speaking, lithography involves removing some materials
from a surface (negative), and patterning involves adding some materials
onto the surface (positive). In most cases, it is not necessary
to distinguish them as in our research. Generally, if the focus
is only on the geometric side, lithography and patterning are the
same. But if the focus is on the material side, the two will have
different meanings.
Q: What is the remarkable advantages of DPN compared with other
methods?
A: (1) small feature, (2) serial working way, (3) material multiplicity.
Q: Why do we shrink sensors?
A: (1) fast response and recovery, (2) higher sensitivity, (3) readily
integrated to compact array for smart sensing.
