“…As compared to their crystalline counterparts, where all In and Ge atoms are octahedrally bonded, the enlarged structural deviation will enhance the thermal stability of amorphous IGT alloys. This observation is consistent with experimental findings, as the crystallization temperature T x of doped InGeTe 2 [49] and undoped InTe thin films [60] is increased to ∼276 and ∼300 • C, respectively, as compared to that of GeTe T x ∼190 • C [87].…”

“…In addition, indium forms a unique PCM In 3 SbTe 2 [55][56][57][58][59] that exhibits metallic behavior in its crystalline phase, but semiconducting behaviors in its amorphous phase, in contrast to conventional PCMs, which remain semiconducting during memory programming. It has been suggested that even InTe could also be a potential PCM for non-volatile electronics [53,60]. In this work, we focus on the InTe-GeTe (IGT) tie line, in particular, the three stoichiometric compositions, namely InGe 3 Te 4 , InGeTe 2 and In 3 GeTe 4 .…”

Chalcogenide phase-change materials (PCMs) based random access memory (PCRAM) enter the global memory market as storage-class memory (SCM), holding great promise for future neuro-inspired computing and non-volatile photonic applications. The thermal stability of the amorphous phase of PCMs is a demanding property requiring further improvement. In this work, we focus on indium, an alloying ingredient extensively exploited in PCMs. Starting from the prototype GeTe alloy, we incorporated indium to form three typical compositions along the InTe-GeTe tie line: InGe3Te4, InGeTe2 and In3GeTe4. The evolution of structural details, and the optical properties of the three In-Ge-Te alloys in amorphous and crystalline form, was thoroughly analyzed via ab initio calculations. This study proposes a chemical composition possessing both improved thermal stability and sizable optical contrast for PCM-based non-volatile photonic applications.

“…Elagin Park is located on Elagin Island at the mouth of the Neva River, where it flows into the Gulf of Finland. In 2012 the park was declared a monument of nature of regional significance "Elagin Island", and the territory, occupied by the park, became a monument of nature of regional importance [Elagin Park, 2023b], and Elagin Palace, situated in the park, is designated as UN-ESCO World Heritage Site [Elagin Park, 2023c]. These formal statuses impose certain limitations on managerial decisions concerning the development of the park.…”

Goal: to develop a framework for customer insight for urban parks that allows to elicit common use patterns as well as needs of various customer segments to increase park management effectiveness. Methodology: in the example of the Elagin Park in St. Petersburg, we show that customer insight by means of principal component analysis and cluster analysis gives possibility to identify non-obvious behavioral patterns of park visitors as well as segment the park visitors. We test our framework by using primary data on 701 respondents, collected by means of CAWI-survey. Findings: the derived segments differ from those which urban parks traditionally consider. The identified behavior patterns and needs of these segments show possible directions for revising the development of the park. Originality and contribution of the authors: this study demonstrates the possibilities of quantitative analysis in determining directions for the development of city parks by the example of on Elagin Park in St. Petersburg, Russia. This fills the gaps in research on managerial approaches in the contemporary urban park development.
