The X-ray diffraction pattern of GeTe2 thin film that have been annealed at 200 °C ( Figure 1) confirms the cubic crystal structure with unit cell constant of a = 11.10 Å which agrees well with...

2017年4月19日 · By analyzing the XRD spectra of crystalline GeTe, we verified that Cm and P1 or R3m coexist in the real system and the relative presence of different structures can be modulated by compressive...

2024年4月15日 · Physical parameters are necessary to determine the suitability of the chalcogenide materials for specific applications. The present study reports the physical characteristics of the multicomponent GeTe 2-x (SeSb) x (x = 0, 0.2, 0.4, 0.6) chalcogenide glasses synthesised by the melt-quench technique.

1987年12月1日 · In this paper, we report stability of crystalline phase of GeTe2 in relation to the film thickness and existence of the substrate. The crystalline GeTe2 cannot be formed in the film with the thickness of more than 6 urn or in the self-supported film.

To better understand factors that affect the crystallization rate, we have investigated crystallization of GeTe films as a function of their deposition temperatures and deposition rates, using...

2013年11月13日 · We have successfully synthesized a single-crystal sample of the layered structure ferromagnet Fe 3 GeTe 2 and present the results of its complete characterization using powder X-ray diffraction (XRD), magnetic susceptibility χ (T), isotherm magnetization 𝑀 (𝐻), specific heat 𝐶 (𝑇), and electrical resistivity ρ (T) measurements.

2022年3月1日 · Fig. 1a is the XRD patterns of GeTe film. It can be seen from figure that there is an obvious diffraction package at 25° and 50° which means GeTe film is typical amorphous structure as-deposited at room temperature. Fig. 1b is the XRD patterns of GeTe film after annealed at 200 °C in Ar/H2 atmosphere.

2016年1月8日 · The magnetic structure and phase diagram of the layered ferromagnetic compound F e 3 G e T e 2 has been investigated by a combination of synthesis, x-ray and neutron diffraction, high-resolution microscopy, and magnetization measurements.

2017年9月14日 · Here, we report the wafer-scale growth of 2D ferromagnetic thin films of Fe 3 GeTe 2 via molecular beam epitaxy, and their exotic magnetic properties can be manipulated via the Fe composition and...

2019年12月1日 · Here, we investigated physical properties of a recently rediscovered ferromagnetic 2D material, Fe5 GeTe 2, which has near-room temperature Tc, such as stability of monolayer, and electronic and magnetic properties as …
