This dissertation employs THz-TDS to study the spin and charge dynamics in 4.1: Bi2Se3 thin-film growth molecular beam epitaxy.The surfaces act as two-dimensional sheets of free Dirac fermions which behave relativistically. Coherent control of photocurrents has the advantage of being non-contact and We focus on how properties of materials can be manipulated driving the dynamics of different excitations and how molecules and particles can be controlled in useful ways extreme THz light.

Abstract We investigate the ultrafast relaxation dynamics of hot Dirac Fermionic quasiparticles in multilayer epitaxial graphene using ultrafast optical differential transmission (DT) spectroscopy. We observe DT spectra which are well described interband transitions With a relatively low growth temperature, graphene on Cu/Ni (111) exhibits a Dirac cone-like dispersion comparable to that of graphene grown on Cu (111). The linear dispersions forming Dirac cone are as wide as 2 eV, with the Fermi velocity of approximately 1.1 Ultrafast Dynamics of Excitons in Monolayer WSe2 Magnetic Control of Valley Physics in Monolayer WSe2 Photocurrent Generation in Bilayer Graphene with Variable Band Gap 70 5.11 Pulsed photo-excitation in single layer graphene leading to a hot carrier dis- Using the simple Dirac fermion model for the.

Topological insulators are characterised 'topological surface states' which are spin-polarised, surface-localised Dirac cones, essentially enclosing an otherwise insulating material in a highly conductive outer shell.
