X‐ray diffraction measurements show that the films with different Ta doping concentrations are (00<jats:italic>l</jats:italic>)‐oriented single‐crystalline β‐Ga<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub> without impurity phases. The incorporation of the Ta element modifies the electrical properties of Ta‐Ga<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub> films significantly. At a very low doping ratio of 0.05 mol%, the Ta‐Ga<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub> film showed a minimum resistivity of 2.32 Ω·cm and a carrier concentration of 2.48×10<jats:sup>17</jats:sup> cm<jats:sup>‐3</jats:sup>. The corresponding activation energy of Ta element in the film was 16.8 meV, suggesting that the Ta element is a promising shallow donor dopant. The XPS analysis confirms that the Fermi level of the Ga<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub> films shifts towards the conduction band minimum after the introduction of Ta ions. These results indicate that the transition metal element Ta could be an effective n‐type dopant for modulating the carrier transport behavior of β‐Ga<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub> films.This article is protected by copyright.

Here, the dependence of the resonance frequency and the maximum RIN at the resonance frequency is studied as functions of the ridge waveguide (RW) and tapered section currents independently. The low frequency RIN is approximately -162 dB Hz^-1, and the RIN peak at currents providing high output power is as low as -154 dB Hz^-1. The observed nonlinearity of the squared resonance frequency with the RW section current is attributed to carrier saturation. The measured high values of the resonance frequency, exceeding 2.5 GHz for RW currents higher than 100 mA at a tapered current of 3 A, indicate gain lever enhancement.","PeriodicalId":54619,"journal":{"name":"Physica Status Solidi-Rapid Research Letters","volume":"35 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140005665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research in this field has been driven by the potential applications in night vision devices, military surveillance, and autonomous vehicles, leading to a growing interest in exploring new materials to bridge the performance gap between cooled photon detectors and uncooled bolometers. This study focuses on the optoelectronic and bolometric characteristics of nanocrystals (NCs) in a colloidal solution. These NCs exhibit a significant change in resistivity (<jats:italic>ρ</jats:italic>) when subjected to temperature variations ranging from 170K to 400K.

Liquid phase exfoliation (LPE) is a common and facile method to prepare 2D MoS₂ and WS₂. Currently, the principally employed solvents for LPE of MoS₂ and WS₂ are expensive, toxic and have high boiling points. These drawbacks encourage to find more sustainable alternatives to the liquid medium used for the preparation of 2D material inks. Water would be the best option, but surfactants are necessary for LPE in water, since MoS₂ and WS₂ are hydrophobic. Organic molecules with amphoteric character such as sodium dodecyl sulfate (SDS), sodium dodecylbenzene sulfonate (SDBS) and sodium hexyl sulfonate (SHS) are selected as suitable candidates for the role of surfactant. However, the study of these surfactants used in LPE is barely systematically reported. In this work, we present a detailed investigation on the impact of these surfactants on the LPE of MoS₂ and WS₂, which are representatives of TMDs. By characterizing and qualifying the products from average number of layers, we find that all the surfactants work efficiently to exfoliate MoS₂ and WS₂ into few layers, and SHS stabilizes the 2D layers better than the other two surfactants. However, in terms of yield and relative surfactant concentration, we don’t identify a real trade-off between maximized quantity of exfoliated materials and minimized surfactant concentration, which prompts to select the colloidal ink based on the specific further needs for processing.","PeriodicalId":54619,"journal":{"name":"Physica Status Solidi-Rapid Research Letters","volume":"1 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139969556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Modified electronic structure of amorphous Mn‐Si‐Te for OTS application: Improved thermal stability by the formation of Mn‐Te bonding","authors":"Kentaro Saito, Shogo Hatayama, Yuta Saito","doi":"10.1002/pssr.202300474","DOIUrl":"https://doi.org/10.1002/pssr.202300474","url":null,"abstract":"A critical element within the 3D Xpoint architecture is the Ovonic threshold switch (OTS) material, which serves a crucial role as a selector. The development of novel OTS materials devoid of hazardous elements such as As and Se is imperative for mitigating environmental impact. The Si‐Te binary telluride is a representative As/Se‐free OTS material, demonstrating stable switching. However, its thermal stability is insufficient for enduring annealing processes in semiconductor manufacturing. To address this challenge, this study proposes the incorporation of Mn into the Si‐Te alloy. While the introduction of transition metals into chalcogenide glass typically reduces the electrical resistivity, potentially compromising the ON/OFF ratio, the off current for the device containing 26 at.% Mn is observed to be lower than that for the undoped Si‐Te device. Furthermore, the thermal stability of the Mn‐Si‐Te film surpasses that of its pristine counterpart. X‐ray photoelectron spectroscopy and density functional theory simulations provide evidence of Mn‐Te bonding formation in the Mn‐Si‐Te amorphous alloy, thus suggesting the role of Mn‐Te bonding in enhancing thermal stability. These findings provide a promising avenue for the advancement of novel OTS materials.This article is protected by copyright.
