Bias Free Gap Creation in Bilayer Graphene
A. R. Davenport, J. P. Hague
For graphene to be utilized in the digital electronics industry the challenge is to create bandgaps of order 1eV as simply as possible. The most successful methods for the creation…
Enhancement of gaps in thin graphitic films for heterostructure formation
J. P. Hague
There are a large number of atomically thin graphitic films with similar structure to graphene. These films have a spread of bandgaps relating to their ionicity, and also to the su…
Polarons in highly doped atomically thin graphitic materials
J. P. Hague
Polaron spectral functions are computed for highly doped graphene-on-substrate and other atomically thin graphitic systems using the diagrammatic Monte Carlo technique. The specifi…
Tunable graphene bandgaps from superstrate mediated interactions
J. P. Hague
A theory is presented for the strong enhancement of graphene-on-substrate bandgaps by attractive interactions mediated through phonons in a polarizable superstrate. It is demonstra…
Tuning correlation effects with electron-phonon interactions
J. P. Hague, N. d'Ambrumenil
We investigate the effect of tuning the phonon energy on the correlation effects in models of electron-phonon interactions using DMFT. In the regime where itinerant electrons, inst…
Breakdown of Migdal--Eliashberg theory via catastrophic vertex divergence at low phonon frequency
J. P. Hague, N. d'Ambrumenil
We investigate the applicability of Migdal--Eliashberg (ME) theory by revisiting Migdal's analysis within the dynamical mean-field theory framework. First, we compute spectral func…
