TL;DR: In this article, a simple solvo-thermal method was used to synthesize undoped and Mn-doped ZnO samples with different percentage of Mn content (1, 2 and 3 mol%) by using X-ray diffraction.

TL;DR: In this article, the structural, chemical and optical properties of ZnO samples were studied by using x-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive xray (EDX) analysis, Fourier transform infrared (FTIR) spectroscopy and UV-VIS spectrography.

TL;DR: In this paper, the formation of ripple structure at high doses s,7ˆ 10 17 ions/ cm 2 d, starting from initiation at low doses s 1ˆ10 17 ion beam, is evident from atomic force microscopy (AFM) and depth-resolved x-ray grazing incidence diffraction (GID), while that in the buried crystalline region below a partially crystalline top layer, the top morphology is conformal with the underlying crystalline ripple.

TL;DR: In this article, the surface and subsurface structure of individual ripples having submicron scale wavelength and nanometer scale amplitude, generated by obliquely incident (50--120 keV) ion bombardment of Si, was studied using cross-section transmission electron microscopy (XTEM).

TL;DR: In this article, the spatial maps of localized surface plasmon resonances associated with photon emission in a truncated tetrahedral gold nanoparticle on a silicon substrate were reported.
