Photoreflectance spectroscopy of BiOCl epitaxial thin films

T. Nishiwaki, T. Makino, Z. Sun +2

We have observed a new optical transition in the photoreflectance spectra of indirect-gap BiOCl thin films, which were grown on SrTiO $_{3}$ substrates. The position of this transitio…

Terahertz emission from transient currents and coherent phonons in layered MoSe $_{2}$ and WSe $_{2}$

Jessica Afalla, Joselito Muldera, Semmi Takamizawa +4

Terahertz (THz) time-domain emission spectroscopy was performed on layered 2H-MoSe2 and 2H-WSe2. The THz emission shows an initial cycle attributed to surge currents and is followe…

Effective and efficient transport mechanism of CO $_{2}$ in subnano-porous crystalline membrane of syndiotactic polystyrene

Yoshinori Tamai

The gas permeation behavior in the single crystal of syndiotactic polystyrene (s-PS) S-I form was investigated in detail, in comparison to that in the s-PS $ε$ form. The…

Effect of heteroepitaxial growth on LT-GaAs: ultrafast optical properties

Jessica Afalla, Elizabeth Ann Prieto, Horace Andrew Husay +8

Epitaxial low temperature grown GaAs (LT-GaAs) on silicon (LT-GaAs/Si) has the potential for terahertz (THz) photoconductive antenna applications. However, crystalline, optical and…

New views of crystal symmetry guided by profound admiration of the extraordinary works of Grassmann and Clifford

Eckhard Hitzer

This paper shows how beginning with Justus Grassmann's work, Hermann Grassmann was influenced in his mathematical thinking by crystallography. H. Grassmann's Ausdehnungslehre in tu…

Reciprocal Space and Crystal Planes in Geometric Algebra

Eckhard Hitzer

This contribution discusses the geometry of $k$ D crystal cells given by $(k + 1)$ points in a projective space $R^{n + 1}$ . We show how the concepts of barycentric and fractional (cry…

New Views of Crystal Symmetry

Eckhard Hitzer

Already Hermann Grassmann's father Justus (1829, 1830) published two works on the geometrical description of crystals, influenced by the earlier works of C.S. Weiss (1780-1856) on…
