One way to increase the efficiency of radiation sources for Ge photonics based on Ge is to stretch it, which allows you to transform Ge into a direct-gap semiconductor. However, the high deformation values necessary for this (biaxial 1.5–1.8% or uniaxial 4.5–5%) for sufficiently thick Ge layers can be realized only locally, using various methods. The paper presents the results of the formation of stress-strain methods of uniaxially stretched Ge microstructures (“microbridges”) of various designs and the study of their radiative properties.

Assessing the Effects of Chemical Composition and Short-Range Ordering on the Tensile Deformation Behavior of Nanocrystalline High-Entropy Alloys Nb–Ta–Hf–Zr: A Combined Study on Molecular Dynamics and Monte Carlo Simulation

Babicheva R., Kumar A., Kiran R. et al., Metallurgical and Materials Transactions A: Physical Metallurgy and Materials Science 2025 Vol. 56 P. 5646–5663

In the work, simulations using Monte Carlo (MC) and molecular dynamics (MD) methods are carried out to investigate the Nb–Ta–Hf–Zr system refractory high-entropy alloys (HEAs). In particular, the effects of chemical composition and grain boundary (GB) network on short-range ordering (SRO) during combined MC/MD modeling of relaxation mimicking diffusion process are investigated on single-crystalline and ...

Fatigue Testing Method for Thin Wires

Аксенов О. И., Fuks A., Волков Н. А. et al., Instruments and Experimental Techniques 2023 Vol. 66 No. 3 P. 121–124

Within the framework of this work, a new method for tensile fatigue testing of thin microwires and wires has been developed in accordance with GOST 25.502-79. The developed method has been tested on amorphous microwires of composition Fe77.5Si7.5B15 in glass insulation. It has been established that the deformation mode in the stress range from 0 to 700 ...

Metastable solitonic states in the strained itinerant helimagnet FeGe

Ukleev V., Yamasaki Y., Utesov O. et al., Physical Review B: Condensed Matter and Materials Physics 2020 Vol. 102 No. 1 P. 014416

Tensile strain is a promising tool for the creation and manipulation of magnetic solitonic textures in chiral helimagnets via tunable control of magnetic anisotropy and Dzyaloshinskii-Moriya interaction. Here, by using in situ resonant small-angle x-ray scattering, we demonstrate that skyrmion and chiral soliton lattices can be achieved as metastable states in FeGe lamella as distinct states under tensile ...

Формирование и исследование локально растянутых Ge микроструктур для кремниевой фотоники

Яблонский А. Н., Вдовичев С. Н., Verbus V. A. et al., В кн.: Труды XXII Международного симпозиума «Нанофизика и Наноэлектроника» 2018 г., Нижний НовгородТ. 2: секция 3.: Н. Новгород: Нижегородский государственный университет им. Н.И. Лобачевского, 2018. С. 837–838.

This work presents the results of the formation of Ge stretched microstructures based on Ge layers grown by MBE on Si (001) and SOI substrates, and the study of their radiative properties. Free-hanging Ge microbridges were obtained by optical lithography, plasma-chemical and selective chemical etching. Measurements of local strain by Raman microscopy showed an increase ...
