Proposal Background
A new beaml
ine for nanoscale spatially resolved angle resolved photoelectron spectros
copy (Nano-ARPES) is proposed as part of the Diamond-II project. ARPES is
a powerful and direct probe of the band structure in solid state materials
\, providing unparalleled information on the important electronic states t
hat govern characteristics including superconductivity and novel states of
matter (e.g. Topological Insulators\, Weyl Semimetals) amongst many other
s. Beamline I05 currently provides world leading capability for ARPES expe
riments and consists of a high resolution (HR) branch and a Nano-ARPES bra
nch. The design of the current Nano-ARPES branch is constrained in a numbe
r of ways\; the smallest size is limited by imaging the photon source on t
he exit slits\, the optimal energy range is different to that on the HR br
anch\, the coherence of the beam is compromised and space constraints limi
t the associated infrastructure such as glove boxes around the equipment.
In addition\, beamline I05 is one of the most highly oversubscribed beamli
nes at Diamond (typically >\;4x). This proposal is to build a fully opti
mised beamline for spatially resolved ARPES at Diamond II that would provi
de beam sizes of <\;100nm to enable measurements on\, for example\, arti
ficially nano-engineered structures or devices under biasing conditions. T
his proposal forms the first phase of expanding the synchrotron based ARPE
S capabilities at Diamond-II\, with the long term
aim of adding spin-resolved ARPES onto the current I05 branchline and implementing lasers for pump-probe experiments. Thi
s will be outlined within the context of a strategic development of ARPES
in the UK.
