Platinum on Pt(111) surface
Title
Platinum
on
Pt(111)
surface
Creator

Date Exhibited

Abstract
This
image
represents
platinum
islands
formed
on
top
of
single
crystal
Pt(111)
surface.
Limited
by the
diffusion
along
the
adatom
island
edges
,
all
islands
are
triangular
shaped.
Our
research
is
focused
on the
formation
of
periodic
arrays
of
platinum
nanoclusters
with a
uniform
size
distribution
on
top
of
metal
substrates.
Platinum
are
deposited
on
top
of
metal
substrate
by
evaporation
of
Pt
rod.
Adatoms
behave
differently
depending
on
which
substrate
is
in
use.
If the
substrate
is
a
single
crystal
surface
,
instead
of
forming
clusters
,
flat
islands
with
only
one
or
two
atomic
layers
are
formed
, as the
image
indicates.
Image
was
obtained
by
scanning
tunneling
microscopy
(STM)
at
room
temperature
,
after
deposition
of
0.4
ML
platinum
on
Pt(111)
surface.
