“…The scattering cross section d $ =d is spin dependent and mixes spin components of the incoming flux. In the general case, this spin dependence is rather complex [21]. However, it simplifies essentially when we expand Eq.…”

“…143 Of course, at these energies, the backscattering cross sections become extremely low, and the instrumental difficulties of these high voltages become far too cumbersome. Mott scattering at low energy (∼300 eV), however, can be effective when scattering from Hg vapor due to diffractive effects creating cross section minima where the Sherman function can become sizable.…”

Professor Alessandra Lanzara, ChairThe electronic spin degree of freedom is of general fundamental importance to all matter.Understanding its complex roles and behavior in the solid state, particularly in highly correlated and magnetic materials, has grown increasingly desirable as technology demands advanced devices and materials based on ever stricter comprehension and control of the electron spin. However, direct and efficient spin dependent probes of electronic structure are currently lacking.Angle Resolved Photoemission Spectroscopy (ARPES) has become one of the most successful experimental tools for elucidating solid state electronic structures, bolstered by continual breakthroughs in efficient instrumentation. In contrast, spin-resolved photoemission spectroscopy has lagged behind due to a lack of similar instrumental advances. The power of photoemission spectroscopy and the pertinence of electronic spin in the current research climate combine to make breakthroughs in Spin and Angle Resolved Photoemission Spectroscopy (SARPES) a high priority .This thesis details the development of a unique instrument for efficient SARPES and represents a radical departure from conventional methods. A custom designed spin polarimeter based on low energy exchange scattering is developed, with projected efficiency gains of two orders of magnitude over current state-of-the-art polarimeters. For energy analysis, the 1 popular hemispherical analyzer is eschewed for a custom Time-of-Flight (TOF) analyzer offering an additional order of magnitude gain in efficiency. The combined instrument signifies the breakthrough needed to perform the high resolution SARPES experiments necessary for untangling the complex spin-dependent electronic structures central to today's condensed matter physics.
