“…A more direct SARPES approach is to actually measure the spin of the photoemitted electrons. There are several approaches to do so, based on different types of scattering effects of spin-polarised electrons from a target and comprehensive reviews can be found elsewhere [26][27][28][29][30] . For the sake of this work it is sufficient to say that for every point of the band structure the expectation value of the spin polarisation of the photoemitted electron can be determined and represented as P = (P x , P y , P z ).…”

A historical review of spin-and angle-resolved photoemission on topological materials is presented, aimed at readers who are new to the field or who wish to obtain an overview of the activities in the field. The main focus lies on topological insulators, but also Weyl and other semimetals will be discussed. Further it will be explained why the measured spin polarisation from a spin polarised state should always add up to 100% and how spin interference effects influence the measured spin texture.

“…Symmetry-breaking systems have been extensively studied and shown to produce novel spin-polarisation effects [1,2]. Experimentally, spin-and angle-resolved photoemission have been used to determine the spin density of two-dimensional systems which lack inversion symmetry [3,4]. Examples of this include the Rashba effect in Au(111) [5], the giant Rashba effect in Bi/Ag(111) [6][7][8][9][10] and the spin-valley polarisation present in transition metal dichalcogenide such as WSe 2 [11][12][13].…”

Two-dimensional hexagonal and oblique lattices were investigated theoretically with the aim of observing differences in the spin expectation values between chiral and achiral systems. The spin-resolved band structures were derived from the energy eigenvalues and eigenfunctions of a Hamiltonian that includes the lattice potential and the spin-orbit interaction. The spin texture of the achiral hexagonal system was shown to have two nonzero components of the spin polarization, whereas all three components were calculated to be nonzero for the chiral system. The longitudinal component, found to be zero in the achiral lattice, was observed to invert between the enantiomorphs of the chiral lattice. A heuristic model was introduced to discern the origin of this inverting spin polarization by considering the dynamics of an electron in chiral and achiral lattices. This model was further used to demonstrate the change in magnitude of the spin polarization as a function of the lattice parameters and an electric field perpendicular to the lattice.

Hard X-ray photoelectron spectroscopy (HAXPES) is establishing itself as an essential technique for the characterisation of materials. The number of specialised photoelectron spectroscopy techniques making use of hard X-rays is steadily increasing and ever more complex experimental designs enable truly transformative insights into the chemical, electronic, magnetic, and structural nature of materials. This paper begins with a short historic perspective of HAXPES and spans from developments in the early days of photoelectron spectroscopy to provide an understanding of the origin and initial development of the technique to state-of-the-art instrumentation and experimental capabilities. The main motivation for and focus of this paper is to provide a picture of the technique in 2020, including a detailed overview of available experimental systems worldwide and insights into a range of specific measurement modi and approaches. We also aim to provide a glimpse into the future of the technique including possible developments and opportunities.
