A systematic review of the crystal chemical properties of the σ phase is presented, with
special emphasis on the atomic order, ie the distribution of the atoms on the different sites of …

Continued downscaling of functional layers for key enabling devices has prompted the
development of characterization tools to probe and dynamically control thin film formation …

Despite extensive studies since the 1960s, the exact mechanisms underlying phase
formation of metastable tetragonal beta-Tantalum (β-Ta) structure commonly found in …

Structural properties of tantalum are of interest because of its potential application in high
temperature wear and erosion. In this paper, we report on beta tantalum coatings, which …

Here, we study the structural and optical properties of tetragonal β-tantalum-sputtered thin
films both ex situ and when exposed to hydrogen, with a focus on optical hydrogen sensing …

We comparatively study the elastic properties of the two existing polytypes of tantalum, α-Ta
(ground state bcc structure) and β-Ta (metastable tetragonal structure), using density …

The metastable tetragonal beta phase of tantalum can be made in thin film form by sputter
deposition and has very different properties from the stable BCC alpha phase. Both phases …

Using a multi-beam optical stress sensor, the real-time stress evolution during the early
growth stages of a large class of sputter-deposited metal (Me) films is studied with …

A combination of electronic-structure methodologies from density functional theory (DFT)
through a tight-binding (TB) model to analytic bond-order potentials (BOPs) has been used …

All thermal vibrations of atoms are in fact anharmonic–this is the underlying reason for the
manifestation of many physical properties of solids, primarily its thermal expansion. By now …
