Electronic phase separation at the LaAlO3/SrTiO3 interface

TL;DR: An EPS state is reported at the LaAlO(3)/SrTiO (3) interface, where the interface charges are separated into regions of a quasi-two-dimensional electron gas, a ferromagnetic phase, which persists above room temperature, and a diamagnetic/paramagnetic phase below 60 K.
Journal ArticleDOI

Mega-electron-volt proton irradiation on supported and suspended graphene: A Raman spectroscopic layer dependent study

TL;DR: Graphene samples with 1, 2, and 4 layers and 1'+'1 folded bi-layers and graphite have been irradiated with 2 MeV protons at fluences ranging from 1'×'1015' to 6'× '1018' ions/cm2.
Journal ArticleDOI

A new route to graphene layers by selective laser ablation

TL;DR: For the 2D regime of graphite (up to N≈7), the dominant flexural mode specific heat (due to its N-1 dependence) gives rise to a strong layer number-dependence on the pulsed laser ablation threshold energy density, while for 3D regime (N>>7) the energy density windows exist between the minimum energy densities that are required for ablating single, bi, or more layers of graphene, allowing layer number selectivity as discussed by the authors.
