In particular, the presence of significant interlayer resistance such as multilayers of ReS2 induces bias-dependent redistribution of conduction channels, resulting in channel migration vertically. Here, we experimentally investigate the contact-geometry-dependent channel migration behavior in multilayer ReS2 field-effect transistors (FETs) using a vertically stacked h-BN/ReS2/h-BN heterostructure. Devices with symmetric top contacts, symmetric edge contacts, and asymmetric (hetero) contact configurations are fabricated on the same flake. Systematic measurements of transconductance (gm), its derivative (dgm), and threshold voltage (Vth), combined with theoretical modeling based on Thomas–Fermi screening and interlayer resistor networks, reveal that top-contacted devices exhibit a downward migration of the main conduction channel with increasing drain bias. In contrast, edge-contacted devices maintain a stable bottom-centered conduction profile, independent of drain bias conditions. In the hetero-contact configuration, where the source electrode is edge-contacted, direct carrier injection into all layers enhances vertical channel selectivity, resulting in earlier onset and more pronounced channel migration even at relatively low drain bias. In addition, the field-effect mobility extracted from gₘ and its agreement with low-field mobility from the Y-function method confirms that interfacial scattering, rather than contact resistance, predominantly limits device performance. This study provides direct experimental insights into vertical charge migration in multilayer 2D materials and offers design guidelines for engineering contact strategies in future 2D FETs. </div>","PeriodicalId":677,"journal":{"name":"Journal of the Korean Physical Society","volume":"87 2","pages":"194 - 200"},"PeriodicalIF":0.9,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145169484","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 present investigation examines the heat transfer of a TiO2/ethylene glycol nanofluid flowing through a receiver tube within a parabolic trough solar collector with the nanoparticles aggregation effect. Solar collectors transform incident sunlight to thermal energy through absorption, which is used for different purposes. The flow within the receiver tube is modeled using a cylindrical surface representation. Furthermore, the analysis considers the impact of natural convection and thermal radiation. To consider the influence of aggregation, revised forms of the Krieger–Dougherty model and the Maxwell and Bruggeman models are applied to estimate the effective viscosity and thermal conductivity of TiO2/ethylene glycol nanofluid, respectively. Nanoparticle aggregates are not exactly spherical, but the aggregate represents an approximation to spherical shape. This information implies that certain uncertainty or fuzziness is involved with the effective volume fraction of NPs aggregates. Therefore, the authors have developed a mathematical model in a fuzzy setting. The fuzzy differential equations are modeled using the triangular fuzzy numbers developed by (alpha)-cut, where (alpha in left[ {0,,1} right]).

The fabrication of gold nanotips has predominantly relied on electrochemical etching, a method offering high yield and low cost, but it suffers from issues such as impurity contamination during processing and the formation of non-uniform tips. In this study, we propose a novel and simple fabrication method for gold nanotips using a meniscus-guided three-dimensional (3D) printing technique. This bottom-up approach uses a liquid meniscus formed between a nanopipette and a substrate to create 3D structures, with precise control over process parameters, enabling the formation of structures with a wide range of diameters, shapes, and configurations. By precisely increasing the pulling speed, it is possible to decrease the diameter of the printed structures. Via two-step 3D printing optimization approach, we successfully fabricated an Au nanotip with a diameter of 100 nm on top of the 3D structure. Our technique offers a robust yet simple new route to fabricate nanotips and opens up a multitude of potential applications in fields such as nano-optics, materials science, and surface analysis.</div>","PeriodicalId":677,"journal":{"name":"Journal of the Korean Physical Society","volume":"87 2","pages":"236 - 242"},"PeriodicalIF":0.9,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145168325","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}

In this work, we investigate the effects of deposition and annealing temperatures on the structural and electrical properties of SnO₂ thin films grown by thermal atomic layer deposition (ALD) using tetrakis(dimethylamino)tin (TDMA-Sn) and ozone (O₃). Films were deposited at 150 ℃ and 200 ℃ followed by post-deposition annealing in O₂ between 400 ℃ and 600 ℃. Crystallographic analysis revealed that higher deposition and annealing temperatures promote rutile phase formation and grain growth, improving carrier concentration and mobility. The optimized sample, which was deposited at 200 ℃ and annealed at 600 ℃, achieved a carrier density of 2.54 × 1022 cm⁻3 and Hall mobility of 51.3 cm2/V·s, resulting in a low resistivity of 1.89 × 10⁻4 Ω·cm.

Thickness uniformity and conformality were also demonstrated, achieving step coverage over 96% and wafer-scale thickness uniformity exceeding 98%.

Notably, the resonance peak position of the AME field remains unaffected by temperature but shifts significantly with electromagnetic wave frequency and magnetic field. The high-frequency electromagnetic wave significantly enhance the AME field, introducing new resonant peaks and modulating the field’s amplitude and position. As the frequency of EMW Ω increases, the resonance peaks shift to higher magnetic field values. The study identifies the cyclotron resonance phenomenon, where the AME field increases sharply at specific magnetic field strengths. This resonance shifts with changes in the electromagnetic wave frequency, indicating a complex interplay between electrons, phonons, and external fields. These findings contribute to perfecting quantum theory and enrich our understanding of the unique properties of SPPSISQW structure, especially highlighting significant differences from conventional bulk semiconductors and other low-dimensional semiconductor structures such as quantum wires and superlattices.
