Transparent
and
Flexible
Oxide
Nano-Electronics
The
oxide
semiconductor
is
becoming
a
key
material
for
future
electronics
because
of
their
wide
band
gap,
hence
high
transparency
and
low
OFF
current,
compared
with
the
ubiquitous
silicon
thin-film
technology.
The
oxide
can
be
processed
at
room
temperature
and
at
low
fabrication
cost,
which
makes
it
amenable
for
integration
on
a
wide
range
of
substrate
materials
including
plastic
and
paper.
This
talk
will
review
the
new
generation
of
applications
of
oxides
ranging
from
large
area
electronics
to
the
newly
emerging
Internet
of
Things.
While
the
oxide
transistor
continues
to
evolve,
producing
devices
with
higher
mobility,
steeper
sub-threshold
slope
and
lower
threshold
voltage,
practical
circuits
are
constrained
by
issues
related
to
non-uniformity,
electrically-
and
illumination-induced
instability,
and
temperature
dependence.
We
will
discuss
the
critical
design
considerations
of
displays,
sensors
and
sensor
interfaces
to
show
how
device-circuit
interactions
should
be
handled
and
how
compensation
methods
can
be
implemented.
In
particular,
the
quest
for
low
power
becomes
highly
compelling
in
newly
emerging
application
areas
related
to
wearable
devices
in
the
Internet
of
Things.
We
will
discuss
thin-film
transistor
operation
near
the
OFF
state,
driven
by
the
pivotal
requirement
of
low
supply
voltage
and
ultralow
power;
the
operation
of
the
wearable
device
is
challenged
by
limited
battery
lifetime
even
if
augmented
with
energy
harvesting.
