Background:

Two-dimensional systems exhibit complex phases and transitions.
Ultrafast structural probing provides insights into internal dynamics and substrate interactions.

Purpose of the Study:

To investigate the structural relaxation dynamics of a polymer/graphene bilayer system out of equilibrium.
To develop and apply ultrafast low-energy electron diffraction (ULEED) for time-resolved analysis.

Main Methods:

Utilized a laser-pump/electron-probe scheme for ultrafast structural probing.
Employed transmission electron diffraction to study a polymer/graphene bilayer.
Excited the system out of equilibrium to observe relaxation dynamics.

Main Results:

Resolved the ultrafast melting of a polymer superstructure on a graphene substrate.
Determined time scales for energy transfer across the bilayer interface.
Observed the loss of superstructure order and formation of an amorphous phase with short-range correlations.

Conclusions:

Ultrafast low-energy electron diffraction is a powerful tool for studying dynamics in two-dimensional systems.
The experimental approach is suitable for a wide range of ultrafast surface science problems.
Understanding interfacial energy transfer and structural dynamics is crucial for advanced materials.
