Ultraviolet B (UVB) light is considered the major environmental inducer of human keratinocyte DNA mutations, including within the tumor-suppressor gene p53, and chronic exposure is associated with cutaneous squamous cell carcinoma (SCC) formation. La

Cutaneous squamous cell carcinoma (SCC) is the most prevalent invasive malignancy with metastatic potential. The epidermis is exposed to a variety of environmental DNA-damaging chemicals, principal among which are polyaromatic hydrocarbons (PAHs) ubi

A Cr(001)/Fe(001) superlattice with ten bilayers grown by molecular beam epitaxy on a Ag(001) substrate is studied by in situ scanning tunneling microscopy (STM) and ex situ x-ray diffraction (XRD). Layer-resolved roughness parameters determined from

We investigate Fe/Cr/Fe(001) trilayers grown on Ag(001)/Fe/GaAs(001) substrates at different temperatures. By changing the substrate temperature of the bottom Fe film during deposition, but otherwise keeping the preparation parameters constant, we ar

Surfaces of amorphous metals are studied by scanning tunneling microscopy (STM). In situ prepared surfaces of amorphous ribbons and splats as well as thin $(l5 \mathrm{nm})$ films show a characteristic morphology that is attributed to the amorphous s

The solid phase epitaxy process from an amorphous binary alloy film on Si(111) to a ternary crystalline silicide overlayer has been studied. Scanning tunnelling microscopy on the atomic scale and low energy electron diffraction show a structural phas

By means of magneto-optical Kerr effect we observe for the first time antiferromagnetic coupling between ferromagnetic layers across an amorphous metallic spacer layer. Biquadratic coupling occurs at the transition from a ferromagnetically to an anti

We report on a comprehensive study of the growth of 5-nm-thick epitaxial Fe(001) films on Ag(001) substrates which are deposited on Fe-precovered GaAs(001) wafers. We characterize the films in situ by scanning tunneling microscopy, low-energy electro

We prepare 150 nm thick epitaxial Ag buffer layers on Fe-precovered GaAs(001) at 380 K. Post-annealing at 570 K improves the morphology of the films, as observed by scanning tunneling microscopy (STM), without changing the chemical composition at the
