Their advantages include large-area fabrication, high current driving capability, mobilities in the range of several tens of cm²/Vs, and simple fabrication processes. However, key performance metrics, such as on-current (I_on), on/off current ratio (I_on/I_off), subthreshold swing (SS), hysteresis, and bipolarity, often involve trade-offs. Although excellent individual performance in these metrics has been achieved, comprehensive optimization, particularly at high drain-to-source voltages (V_ds), has been limited. In this study, we explore these critical trade-offs by optimizing the dielectric and passivation layers of CNT TFTs. Using a dielectric stack of HfO₂/SiO₂ and a passivation stack of SiO₂/Y₂O₃, we achieve CNT TFTs with optimal performance. Typical devices with a 10 μm channel length (L_ch) demonstrate an average I_on of ∼1.2 μA/μm, I_on/I_off exceeding 10⁶ for V_ds of −0.1 V and 10⁵ for V_ds of −4.1 V, SS of ∼180 mV/dec, hysteresis of ∼0.5 V, and minimal bipolar behavior, and reducing L_ch to 2 μm improves the average I_on to ∼16.4 μA/μm, representing the highest overall performance for CNT TFTs with micrometer channel lengths. Additionally, we demonstrate effective modulation of μLEDs by these TFTs. This work guides further advancements in CNT technology for display driving applications.</div></div>","PeriodicalId":262,"journal":{"name":"Carbon","volume":"237 ","pages":"Article 120154"},"PeriodicalIF":10.5,"publicationDate":"2025-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143487291","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we report for the first time the induced ferroelectricity in free-standing Mo₂Ti₂C₃T_x MXene film after undergoing simple heat treatment and its utilization as an active functional layer for non-volatile resistive random-access memory. The ferroelectric response, oxide phase formation and memory storage kinetics of the free-standing heated Mo₂Ti₂C₃T_x film outperformed the pristine non-heated Mo₂Ti₂C₃T_x. Ferroelectric behavior was observed solely in heated Mo₂Ti₂C₃T_x owing to the formation of TiO₂ with typical butterfly dielectric constant loop. Specifically, by utilizing the adaptive property of graphene oxide to reduce into conductive graphene sheets amid laser scribing, a tri-layer memristor structure Laser reduced graphene/heated Mo₂Ti₂C₃T_x/Laser reduced graphene was fabricated and analyzed against the Laser reduced graphene/non-heated Mo₂Ti₂C₃T_x/Laser reduced graphene device scheme. The former tri-layer free-standing scheme exhibited controlled conduction filament formation showcasing excellent resistive switching, sufficient memory window of R_off/R_on = 10² and excellent cycle-to-cycle endurance of up to 10³ cycles. This finding reveals the remarkable potential of double transition MXenes to be used as functional middle layer, which was not yet explored in resistive RAM memory storage elements, hence opening the door for another domain of applications i.e. neuromorphic computing and ferroelectronics based on non-volatile memory.</div></div>","PeriodicalId":262,"journal":{"name":"Carbon","volume":"237 ","pages":"Article 120149"},"PeriodicalIF":10.5,"publicationDate":"2025-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143519259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
