| 2 | QUANTUM MECHANICAL MODEL AND SIMULATION OF GaAs/AlGaAs QUANTUM WELL INFRARED PHOTODETECTOR-Ⅱ ELECTRICAL ASPECTS显示文摘A complete quantum mechanical model for GaAs/AlGaAs quantum well infrared photodetectors(QWIPs) was presented. The photocurrent was investigated by the optical transition(absorption coefficient)between the ground state and the excited states due to the nonzero component of the radiation field along the sample growth direction. By studying the inter diffusion of the Al atoms across the GaAs/AlGaAs heterointer faces, the mobility of the drift diffusion carriers in the excited states was calculated. As a result, the measurement results of the dark current and the photocurrent spectra are explained theoretically. | Fu Y Willander M LU W | 2002 | 红外与毫米波学报2002,21,6: | 4 |
| 3 | Interoperability of Design Intent in Integrated Product and Process Design显示文摘Concurrent engineering is currently an overwhelming t rend in product development since it takes the down-stream product development issues and product life-cycle issues into consideration in up-front design pro cess. At this stage, evaluation, verification and validation of design concepts and design schemes is critical to the right-to-market product development. I dentification and extraction of design intent from the part digital mock-ups in different data formats and created in different CAD systems for DFX considerati on, evaluation, verification, and validation is crucial too. Traditionally, fro m manufacturing point of view, feature identification and extraction is to get t he features and feature-related information for manufacturing planning and inte gration. Presently, from the viewpoint of product development and product servi ce life cycle, design intent identification and extraction is to get all the des ign-related information for DFX consideration in early design stage, such as de sign for assembly, design for service, design for tooling, design for functional ity and design for environment etc. Therefore, how to successfully extract desi gn intent such as design and machining features and design-related information from the prototyping digital mock-ups created by different CAD systems for DFX consideration in upstream design stage is a very useful topic in integrated prod uct and process design and development. Presently, there are heterogeneous CAD systems in the market and the interoperat ion among the different CAD systems is indispensable. The interoperability of d ifferent CAD systems is by way of data exchanged technology such as STEP and IGE S. The critical weakness of this interoperation technology is that much of the design intent is lost in the interoperation process. Once the product digital m ock-ups is exchanged via data exchange technology such as IGES or STEP, the des ign intent including the dimension-driven design features and other attributes embedded in the part model are lost in the data translation process. Models rea d out of CAD systems come into other systems as featureless chunks of geometry e ntities. Obviously, the interoperation technology does not satisfy the industry need. It has been reported that this poor interoperation technology, which pro vides poor CAD models in neutral-format geometry had cost the automobile indust ry alone $1 billon per year. Fortunately, some researchers have been aware of t he criticality of this since only the United States industry spends billons of d ollars as a result of poor interoperability between computer-aided engineering software tools. In the past, product development was often done within a single company by co-located design team. In more recent years, there has been a busi ness paradigm shift in product development as the product development is being d one more often by geographically and temporally distributed design teams. There is a high level of outsourcing, not only of manufacturing but also of actual pr oduct development effort. Besides, product development across companies, and ev en within a single company, is often done within a heterogeneous software tool e nvironment. How to improve the interoperability of design intent created in het erogeneous software tool environment geographically has become a critical issue in next-generation product development system. Design intent in this research is defined as the outcome of design process. Des ign process goes from the identification of needs to satisfaction of that needs. Design intent satisfies this kind of needs. In this research, design intent i s created in a CAD system and embedded in part CAD model. The detailed design i ntent here includes design and manufacturing features and the feature-relat ed information such as feature parameters, feature relationships and some relate d characteristics such as associativity.

| 4 | QUANTUM MECHANICAL MODEL AND SIMULATION OF GaAs/AlGaAs QUANTUM WELL INFRARED PHOTO-DETECTOR-ⅠOPTICAL ASPECTS显示文摘A complete quantum mechanical model for GaAs?AlGaAs quantum well infrared photodetectors(QWIPs) is presented here. The model consisted of four parts: (1) Starting with the description of the electromagnetic field of the infrared radiation in the QWIP, effective component of the vector potential <| A z |> along the QWIP growth direction ( z axis) due to the optical diffraction grating was calculated. (2) From the wave transmissions and the occupations of the electronic states, it was discussed that the dark current in the QWIP is determined by the drift diffusion current of carriers thermally excited from the ground sublevel in the quantum well to extended states above the barrier. (3) The photocurrent was investigated by the optical transition (absorption coefficient between the ground state to excited states due to the nonzero <| A z |> ). (4) By studying the inter diffusion of the Al atoms across the GaAs?AlGaAs heterointerfaces,the mobility of the drift diffusion carriers in the excited states was calculated, so the measurement results of the dark current and photocurrent spectra can be explained theoretically. With the complete quantum mechanical descriptions of (1 4), QWIP device design and optimization are possible. | Fu Y Willander M Li Ning Lu W | 2002 | 红外与毫米波学报2002,21,5: | 2 |
