Simple, robust and systematic QCA clocking scheme for area-efficient nanocircuits

引用

International Journal of Electronics Letters 2025年第2期13.0卷 210-218页

Quantum-dot cellular automata (QCA) represent an innovative forefront in nanotechnology, exploring the utilisation of quantum dots as carriers of data in computational systems. Temporal controls govern the coordination of information transmission and synchronisation within QCA circuits. Nevertheless, most research in QCA overlooks the crucial aspect of appropriately arranging the fundamental clocking mechanism. Consequently, QCA circuits often exhibit irregularities in their clocking regions, rendering them unsuitable for practical implementation. Adopting a consistent and scalable clocking framework is necessary to address this challenge and facilitate efficient design with optimal routing possibilities within clocking zones. Without a clearly defined and standardised clocking structure, QCA circuit designs remain incomplete and lack viability for fabrication. Numerous QCA clocking methodologies have been proposed, showcasing commendable ingenuity. Nonetheless, these approaches exhibit room for enhancement, particularly in tackling issues concerning design intricacies, such as establishing robust feedback loops and efficient area utilisation. A novel approach termed Simple, Robust and Systematic (SRS) scheme has been introduced in response to these challenges. Emphasising heightened feedback pathways, optimal spatial allocation and streamlined design, this scheme aims to overcome existing limitations. © 2025 Informa UK Limited, trading as Taylor & Francis Group.

SA508Gr.4 N steel is commonly used in nuclear pressure vessels. The current study discloses the impact of austenitizing temperature on its martensitic transformation. Various austenitizing temperatures were employed to examine the martensitic transformation at different experimental conditions. The characteristics of grain boundaries, microstructure, transformation kinetics, and crystallography of the martensitic phase following the austenitizing process and martensitic transformation were analyzed. Austenitizing temperatures had minimal effects on the critical temperature of the austenitizing phase transition. However, an increase in austenitizing temperature resulted in larger grain sizes. The phase composition primarily consisted of lath martensite, accompanied by a small amount of residual austenite (RA). As the austenitizing temperature increased, the temperature of martensite-start temperature (Ms) initially decreased and then increased. On the other hand, the temperature of martensite-finish (Mf) showed no significant sensitivity to changes in the austenitizing temperature. Moreover, the average size of the lath martensite structure was increased, and there was an increased tendency for variant selection as the austenitizing temperature increased, and the combination of specific orientation relationships appeared. This study is very valuable for revealing the microstructure evolution at different temperatures.
