Topography of Crystal Faces

X-ray topography of subsurface crystal layers1

New capabilities of the Berg–Barrett topographic method are demonstrated using a skew-asymmetric X-ray diffraction scheme for investigating structural changes near the surface of semiconductor materials. Specifying the X-ray extinction depth, the details of defects and strains are revealed with high resolution. Consequently, analysis of structural distortion of layers near the surface after var...

Live X-Ray Topography and Crystal Growth of Silicon

Spontaneous water oxidation at hematite (α-Fe2O3) crystal faces.

Hematite (α-Fe2O3) persists as a promising candidate for photoelectrochemical water splitting, but a slow oxygen evolution reaction (OER) at its surfaces remains a limitation. Here we extend a series of studies that examine pH-dependent surface potentials and electron-transfer properties of effectively perfect low-index crystal faces of hematite in contact with simple electrolyte. Zero-resistan...

Multiple faces of narcissistic leadership in Medical Education

Narcissism, being the critical part of the toxic leadership paradigm,has its own impact in the education sphere. Contrastingly,leader’s narcissism cannot be simply underweighted because suchleaders often tend to be creative strategists who can take riskychallenges to suffice the self-ego and leave behind a legacy aswell. This commentary intends to portray the complex mosaic ofthe positive and n...
