TL;DR: The parabolic growth rate of the (110) faces of thin octacosane crystals growing from a light petroleum ether solution is characteristic of growth mechanisms due to dislocations.

TL;DR: In this article, the rate of thickness increase of birefringent crystals placed between crossed polarizers is measured photoelectrically, and the sensitivity is improved by rotating the polarizer and amplifying the photocell current by a tuned ac amplifier.

TL;DR: In this paper, the origin of screw dislocations is ascribed to the climbing of screws under the small supersaturation of vacancies which form in the crystals during cooling, and a generation mechanism of screw or quasi-screw dislocation associated with the boundary migration of secondary crystals (38° (22°) 〈111〉 Kronberg-Wilson boundary) is also described.

TL;DR: In this paper, the interband optical conductivity of granular deposits of lithium at room temperature is investigated and the results obtained at 6 K are different from the theoretical predictions and may be explained on the basis of a phase change in lithium at low temperature.

TL;DR: In this article, a theoretical model was proposed to calculate the cell size in which it is directly related to the specific energy of the sub-boundaries, which are concomitant with the cells.

TL;DR: In this paper, a study of the interface Sn-SnTe showed that it is not possible to see misfit dilocations along [100]Sn at the interface between the tin islands and the substrate.
