However, the severe quantum-confined stark effect (QCSE) and carrier localization make it challenging for micro-LEDs to achieve both high modulation bandwidth and high external quantum efficiency (EQE). Herein, GaN-based freestanding micro-LEDs with varying quantum barrier (QB) thicknesses were designed and fabricated. The thinner QBs effectively reduce the QCSE and improve carrier transport, resulting in high modulation bandwidth and less efficiency droop. Homoepitaxial growth of micro-LEDs gives birth to further improved modulation bandwidth and optical power due to lower defect density and improved thermal dispassion.

With HZO being incorporated in multiple applications, grain size reduction has become essential to enhance the ferroelectric performance and scalability. A common method is implementing a dielectric interlayer (IL) in the middle of HZO films while sacrificing operating power caused by voltage drop across the additional material. This research implemented W and Mo metal ILs in the middle of the HZO stack to prevent grain growth. The effects of the ILs on ferroelectric performance were studied using metal-ferroelectric–insulator-silicon structure. Transmission electron microscopy (TEM) and grazing-incidence X-ray diffraction were used to examine the grain formation in HZO. The results show that metal ILs have successfully improved the ferroelectric performance by suppressing the nonferroelectric monoclinic phase while promoting the formation of the orthorhombic phase. The sample with W IL acting as electrodes for both upper and under HZO thin films was more resilient to fatigue than that with the Mo IL. Hence, W metal ILs can enable HZO implementation in a wider range of application.","PeriodicalId":13092,"journal":{"name":"IEEE Transactions on Electron Devices","volume":"71 11","pages":"6647-6651"},"PeriodicalIF":2.9,"publicationDate":"2024-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142517988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To understand the physical mechanism of isolation, the experimental analysis of isolation structures is done in this work. This article presents the measured leakage current and breakdown characteristics of isolation structures, compatible with lateral devices. For unimplanted isolation structures, leakage is injection barrier limited and breakdown is by surface punchthrough. BV has a quadratic dependence on the isolation length. Ion implantation introduces trap-limited hopping conduction, marked by the exponentially field-dependent conductance. After implantation, despite an increase in leakage current, BV increases drastically. The dependence of BV on isolation length changes from quadratic in unimplanted isolation to linear in implanted one due to flattening of E-field. To achieve high BV in GaN lateral power devices, the implanted isolation structure is preferred at the cost of high isolation leakage.","PeriodicalId":13092,"journal":{"name":"IEEE Transactions on Electron Devices","volume":"71 11","pages":"6915-6920"},"PeriodicalIF":2.9,"publicationDate":"2024-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142579209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
