Patent number: 11974512Abstract: A preparation method of a silicon-based molecular beam heteroepitaxy material, a memristor, and use thereof are provided. A structure of the heteroepitaxy material is obtained by allowing a SrTiO3 layer, a La0.67Sr0.33MnO3 layer, and a (BaTiO3)0.5—(CeO2)0.5 layer to successively grow on a P-type Si substrate. The silicon-based epitaxy structure is obtained by allowing a first layer of SrTiO3, a second layer of La0.67Sr0.33MnO3, and a third layer of (BaTiO3)0.5—(CeO2)0.5 (in which an atomic ratio of BaTiO3 to CeO2 is 0.5:0.5) to successively grow at a specific temperature and a specific oxygen pressure. The preparation method of a silicon-based molecular beam heteroepitaxy material adopts pulsed laser deposition (PLD), which is relatively simple and easy to control, and can achieve the memristor function and neuro-imitation characteristics. A thickness of the first buffer layer of SrTiO3 can reach 40 nm.Type: GrantFiled: February 18, 2022Date of Patent: April 30, 2024Assignee: Hebei UniversityInventors: Xiaobing Yan, Haidong He, Zhen Zhao

Patent number: 10911985Abstract: The application provides a service data splitting method and apparatus. A SeNB receives distributed service data from an MeNB based on a first expected volume of distributed data, and buffers the distributed service data. The SeNB determines a data volume change status of the distributed service data when a preset period expires, where the data volume change status includes a buffered-data volume reduced state, a buffered-data volume accumulated state, and a received-data volume insufficient state. The SeNB adjusts the first expected volume of distributed data based on the data volume change status to obtain a second expected volume of distributed data. and the SeNB sends the second expected volume of distributed data to the MeNB, so that the MeNB performs splitting based on the second expected volume of distributed data.Type: GrantFiled: December 14, 2018Date of Patent: February 2, 2021Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventor: Haidong Yan
