CoFe2O4/buffer layer ultrathin heterostructures on Si(001)

Ultrathin-layer chromatography.

The development of ultrathin-layer silica gel plates with a monolithic structure opens up a new dimension in thin-layer chromatography (TLC). The very small layer thickness of approximately 10 microm and the absence of any kind of binder in combination with the framework of this stationary phase lead to new and improved properties of these ultrathin-layer chromatographic (UTLC) silica-gel plate...

High Photovoltaic Quantum Efficiency in Ultrathin van der Waals Heterostructures.

We report experimental measurements for ultrathin (<15 nm) van der Waals heterostructures exhibiting external quantum efficiencies exceeding 50% and show that these structures can achieve experimental absorbance >90%. By coupling electromagnetic simulations and experimental measurements, we show that pn WSe2/MoS2 heterojunctions with vertical carrier collection can have internal photocarrier co...

Tunable magnetic properties in ultrathin Co/garnet heterostructures

Ultrathin oxide films by atomic layer deposition on graphene.

In this paper, a method is presented to create and characterize mechanically robust, free-standing, ultrathin, oxide films with controlled, nanometer-scale thickness using atomic layer deposition (ALD) on graphene. Aluminum oxide films were deposited onto suspended graphene membranes using ALD. Subsequent etching of the graphene left pure aluminum oxide films only a few atoms in thickness. A pr...

Inter-Layer Potential for Graphene/h-BN Heterostructures Supplementary Information

As described in the main text the force-field parameterization has been performed using the tier-2 basis set, 1 as implemented in the FHI-AIMS suite of programs, 2 with tight convergence settings. This basis set is known to introduce minor basis set superposition errors (BSSE) in dimer calculations. 3, 4 In order to estimate the BSSE in the present case, we have performed counterpoise (CP) 5, 6...
