Nanomechanical characterisation of single‐crystal Bi2Se3 topological insulator

Micro &Nano Letters, Volume 16, Issue 3, Page 203-212, 4 March 2021., 2021
Abstract Topological insulators (TIs) are recently discovered high‐tech materials where their potential use in nanoelectronic devices such as spintronics and quantum computers, due to their unique electronic features, can be a solution to the emerging need for high‐bit data processing.

Influence of Oxygen on Sputtered Titanium‐Doped Indium Oxide Thin Films and Their Application in Silicon Heterojunction Solar Cells

Solar RRL, Volume 5, Issue 1, January 2021., 2021
Radio frequency magnetron sputtered titanium‐doped indium oxide (ITiO) films are fabricated in a low‐temperature process. Oxygen flow ratio plays a vital role in the influence of ITiO crystalline growth, as well as optoelectronic properties. It is demonstrated that ITiO films in the front of silicon heterojunction solar cells result in better ...

Destabilization of free convection by weak rotation [PDF]

, 2011
This study offers an explanation of a recently observed effect of destabilization of free convective flows by weak rotation. After studying several models where flows are driven by a simultaneous action of convection and rotation, it is concluded that ...

Jan Czochralski, the pioneer of crystal research [PDF]

Europhysics News, 2011
Jan Czochralski (1885-1953) was born in Kcynia near Bydgoszcz (Kujawy and Pomorze district in Poland), roughly halfway between Warsaw and Berlin. His seminal work on metallic single crystals and their growth rates was published in Zeitschrift fur physikalische Chemie, received for publication in August 1916, but not published until two years later [2].

Dynamical X‐ray diffraction imaging of voids in dislocation‐free high‐purity germanium single crystals

Journal of Applied Crystallography, Volume 53, Issue 4, Page 880-884, August 2020., 2020
White beam X‐ray topography has been performed to provide direct evidence of micro‐voids in dislocation‐free high‐purity germanium single crystals. A general method is proposed to verify the presence of voids for any crystalline material of high structural perfection.White‐beam X‐ray topography has been performed to provide direct evidence of micro ...

Spiral Crystal Growth in the Czochralski Process—Revisited, with New Interpretations

Crystal Research and Technology, Volume 55, Issue 2, February 2020., 2020
This review deals first with the spontaneous transition of cylindrically growing Czochralski crystals to the growth in spiral morphology. Further, the growth of a full spiral is described considering the azimuthal growth in the off‐centered rotating melt meniscus.
