摘要： This invention provides a process for growing Ge epitaxial layers on Si substrate by using ultra-high vacuum chemical vapor deposition (UHVCVD), and subsequently growing a GaAs layer on Ge film of the surface of said Ge epitaxial layers by using metal organic chemical vapor deposition (MOCVD).The process comprises steps of, firstly, pre-cleaning a silicon wafer in a standard cleaning procedure, dipping it with HF solution and prebaking to remove its native oxide layer. Then, growing a high Ge-composition epitaxial layer, such as Si0.1Ge0.9 in a thickness of 0.8 μm on said Si substrate by using ultra-high vacuum chemical vapor deposition under certain conditions. Thus, many dislocations are generated and located near the interface and in the low of part of Si01.Ge0.9 due to the large mismatch between this layer and Si substrate.Furthermore, a subsequent 0.8 μm Si0.05Ge0.95 layer, and/or optionally a further 0.8 μm Si0.02Ge0.98 layer, are grown. They form strained interfaces of said layers can bend and terminate the propagated upward dislocation very effectively. Therefore, a film of pure Ge is grown on the surface of said epitaxial layers.Finally, a GaAs epitaxial layer is grown on said Ge film by using MOCVD.

摘要： Aspects of the present disclosure provide techniques for constructing a scalable model of an indoor space using crowd-sourced inertial navigation system (INS) signals from mobile devices. By tracking INS signals from a number of participating users, the user's trajectories can be estimated as they move their mobile devices indoors. The estimated trajectories can be scored against similar routes taken by other users. Routes with the highest scores are then laid out over a map of the indoor space to identify areas most often traveled to and from landmarks and distances between the landmarks.

摘要： Systems, methods, and machine-readable media for monitoring the locations of a number of entities are provided. The system may be configured to track the locations of a multitude of entities by grouping entities together into clusters of entities based on their geographic proximity and trajectories. A member of a cluster may be identified as a leader or a follower. The system may receive a number of location reports for the entities and update the locations of the entities based on whether the entity is a leader or a follower. For example, the system may update a back-end location database with the location information for a leader while location updates for followers may be converted into locations that are relative to the corresponding leader's and cached at the system.

摘要： A method for fabricating submicron T-shaped gates for the field-effect transistors disclosed, which can be accomplished by using a tri-layer positive photoresist with a single electron beam exposure and a single development step. Therefore, the cost can be reduced and the yield can be raised for fabricating high speed field-effect transistors. The method comprises the steps of: (i) sequentially spinning coating a first photoresist layer, a second photoresist layer and a third photoresist layer on the top of epitaxial layers, wherein the second photoresist layer is thicker than the third photoresist layer, and the third photoresist layer is not thicker than the first photoresist layer, the viscosity of the second photoresist layer is larger than that of the first and third photoresist layers, and the electron beam sensitivity of the second photoresist layer is larger than that of the first and the third photoresist layers; (ii) exposing all the gate stripe region of the photoresist layers by a single electron beam exposure; (iii) using a developer to develop all the exposed positions of the three photoresist layers by a single development step, so that a T-shaped opening is formed; (iv) etching and removing a contact layer of the epitaxial layers under the T-shaped opening; (v) evaporating gate metal layers to cover the third photoresist layer and to fill the T-shaped opening; (vi) removing the photoresist layers to lift off the evaporated metal layers so that the submicron T-shaped gate is obtained.
