Nano Surface Physics

Convenor: Gavin Bell

Module Code: NS1

Duration: the module will run in 2018-19 as an online-only course. It will be available in Term 2.

Module Details

The aim is to introduce students to aspects of surface physics and thin films. It will not involve much "advanced" condensed matter physics, building on undergraduate CMP understanding. The course will be delivered via Warwick's Moodle. Students from other institutions will be able to sign up for the module's Moodle page using their local email address. You will do guided reading (main text: Modern Techniques of Surface Science, D.P. Woodruff) and formative problem sets. Final assessment will be via an upload of solutions to problems.

Section 1: Introduction and surface and thin-film structure

Motivation, ultra-high vacuum, electron and X-ray interactions with surfaces.

Crystallography: from bulk to surface.

Surface relaxation and reconstruction.

Case studies of surface reconstruction.

Section 2: Surface and thin-film diffraction

Low energy electron diffraction (LEED).

Reflection high energy electron diffraction (RHEED).

Surface and thin-film X-ray diffraction (SXRD, GIXRD).

Case studies of LEED and RHEED pattern interpretation.

Section 3: Thin film growth

Surface growth: underlying theory from thermodynamics to atomistics.

Case study: 2D materials.

Note - this section links to the Epitaxy Fundamentals module but focuses more on underpinning theory.

Section 4: Surface chemical analysis

Why is surface chemical analysis important?

X-ray photoelectron spectroscopy: theory and practice.

Interpretation and fitting of XPS spectra.

Example - "not just nearly clean, but really clean"... how to get an atomically clean surface.
