Relaxation dynamics of amorphous phase change materials

LM thesis proposal Supervisor: Giacomo Baldi In the last years, phase-change non-volatile memory devices have risen important attention for technological applications [1]. They are made by phase-change materials (PCMs), a class of functional materials that are reversibly and rapidly switched between amorphous and crystalline states by electrical pulses in a short timescale of a few …

Inelastic neutron scattering study of the origin of two-level systems in the atomic dynamics of strong glasses

LM thesis proposal Supervisors: Marco Zanatta & Giacomo Baldi At the macroscopic scale, an amorphous solid can be considered as an isotropic continuum and sound wave propagation is well described by the usual elasticity theory. However, the thermal properties at low temperatures (below 1 K) are heavily affected by the presence of two-level states whose …
