The hardware implementation of CNN functionalities with conventional CMOS based devices still lags in area and energy efficiency. This has necessitated the investigations of unconventional devices, circuits, and architectures to efficiently mimic the functionality of neurons and synapses for neuromorphic applications. Spin-orbit torque magnetic tunnel junction (SOT-MTJ) device is capable of achieving energy and area efficient rectified linear unit (ReLU) activation functionality. This work utilizes the SOT-MTJ based ReLU for activation and max-pooling in a single unit to eliminate the need of dedicated hardware for pooling layer. Moreover, 2 × 2 multiply-accumulate-activate-pool (MAAP) is implemented by using four activation pairs each of which is fed by the crossbar output. The presented approach has been used to implement various CNN architectures and evaluated for CIFAR-10 image classification. The number of read/write operations reduce significantly by 2X in MAAP based CNN architectures. The results show that the area and energy in MAAP based CNN is improved by at least 25% and 82.9%, respectively, when compared with conventional CNN designs.","PeriodicalId":446,"journal":{"name":"IEEE Open Journal of Nanotechnology","volume":"4 ","pages":"102-108"},"PeriodicalIF":1.7,"publicationDate":"2023-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/iel7/8782713/10007543/10081384.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"3516685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An analytical model is developed for both upstate and downstate of switch by including parasitic and fringing field capacitance in parallel plate capacitance model. The proposed analytical model includes the ligament efficiency term directly in the formula which reduce the efforts to calculate it individually for various perforation sizes. The capacitance analysis has been carried out by varying the physical parameters to optimize the switch dimensions and these analytical results are compared with the simulation results carried out by 3D FEM tool COMSOL multiphysics for validation. The proposed analytical model results are then compared with benchmark models to understand the efficiency of proposed model in estimating the up and downstate capacitances. The proposed analytical model proved to be good with less error percentage of 2.13% at upstate and 2.59% at downstate whereas the other benchmark models gives greater than 5% error. The switch is then fabricated using 4-mask surface micromachining process and experimental evaluation of capacitance at both upstate and downstate is carried out by DC probe station. Experimentally, the upstate capacitance is obtained as 37.4 fF and downstate as 2.43 pF and the analytical models exhibited low error percentage of 3.95% at upstate and 2.05% at downstate condition for µ = 0.5.","PeriodicalId":446,"journal":{"name":"IEEE Open Journal of Nanotechnology","volume":"4 ","pages":"81-94"},"PeriodicalIF":1.7,"publicationDate":"2022-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/iel7/8782713/10007543/09999329.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"3515039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, using first-principle calculations based on density functional theory (DFT), the variance in MAE and other magnetic properties is observed for transition metal (TM) doped bismuth monolayer (bismuthene). This doped system shows a significant modulation in the magnetic moment, MAE, Curie temperature \u0000<italic>Tc\u0000, and charge transfer. However, Mn-doped bismuthene exhibits half-metallicity with a maximum magnetic moment of 4μB (Bohr magneton) that is 17% higher than Fe-doped bismuthene. The maximum MAE extracted for Mn-doped bismuthene is 27.51% higher than the Ti-doped system. On the basis of these findings, the electronic and magnetic characteristics of Mn-doped bismuthene (Mn-Bi) and monolayer CrI\u00003\u0000 van der Waals (vdW) heterostructures are also investigated. In Mn-Bi/CrI\u00003\u0000 van der Waals heterostructure, the half-metal Mn-Bi can induce the half-metallicity in CrI\u00003\u0000 through charge transfer. Compared to other doped systems, Mn-Bi presents the most favorable magnetic properties. Thus, Mn-Bi/CrI\u00003\u0000 heterostructure paves the path for the development of spintronic devices.","PeriodicalId":446,"journal":{"name":"IEEE Open Journal of Nanotechnology","volume":"4 ","pages":"1-9"},"PeriodicalIF":1.7,"publicationDate":"2022-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/iel7/8782713/10007543/09996563.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"3507987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
