XPS/UPS/REELS system with a sample preparation chamber. Sample stage in the
main chamber is designed to heat or cool a substrate. In the preparation
chamber, we can deposit various materials on a substate. Fast entry chamber
enables us to mount samples upto six at one time. There is an apparatus for
UV-ozone treatment in the fast entry chamber. In 2010 the old analyser is
replaced by PSP Resolve 120.
Photoemission Spectrometer and...
This is a multipurpose monster with two preparation chambers
and two analysis chambers. Four-axis sample manipulator is mounted on the
main analysis chamber with SCIENTA (SES-100) analyzer and x-ray/UV sources.
After deposition of target materials, we can transfer the sample into the
photoemission chamber or PEEM chamber. Using the PEEM, energy resolved
local areal information can be achieved with the combination of laser
pulses. In the photoemission chamber, there is a low energy electron gun
and a photon detector for inverse photoemission (IPES) and reflection
electron energy loss spectroscopy (REELS). We call it total electron
structure measurement system.
Pulsed Laser system
Ti:S oscillator, laser pulses with a duration of hundred
femtoseconds are generated. Through frequency doubling or tripling,
we carry out single-color or two-color pump-probe experiments (2PPE) on a
various surface system.
source and photo-detector take photoluminescence (PL) from a sample. The sample
temperature and other environments are controllable during the measurement.
