The authors attempt to portray the nature of semiconductor research at Bellcore and the ways in which this research serves Bellcore and its seven owners. The semiconductor research at Bellcore supports the Regional Companies' long-range vision of broadband, intelligent, and friendly networks. Through the ideas and information emerging from this research, Bellcore and the owners get some of the clearest early indicators of the shape and performance of networks and services to come. Besides specialized information provided to other Bellcore organizations and the owners, experimental models of new devices are incorporated into Bellcore's system experiments. Examples of research results are described in the areas of VLSI design, photonic and high-speed electronic devices, and integrated optoelectronics and novel optical devices. The values of the consortium mode to both the owners and the research activity itself are briefly reviewed  相似文献

1977年人们发现通过掺杂可以使聚乙炔膜的电导率提高 1 2个量级 ,由绝缘体变成导体 ,从此掀起了有机半导体的研究热潮。其研究工作包括有机高分子材料、有机小分子材料和有机分子晶体材料的电学、光学等性质。有机半导体中的载流子除了电子和空穴外 ,还有孤子、极化子等。人们已经获得低温迁移率高达 1 0 5cm2 /V.s的高质量有机半导体晶体 ,在其中观察到量子霍尔效应 ,并用其制成有机半导体激光器。如今有机半导体彩色显示屏已进入实用阶段。  相似文献

Research into compound semiconductors, as with all areas of scientific research, has a relatively short history in Mexico. Despite this, however, it is actively and successfully pursed at institutions such as Mexico City's CINVESTAV (Centre for Research and Advanced Studies). Prof. Isaac Hernándes-Calderón of the Centre's Physics Department, and director of the MBE group, outlines the ongoing studies of advanced semiconductors at CINVESTAV, focusing on the Physics Department, and provides some insights into the status of science research in Mexico.  相似文献

The Microelectronics and Computer Technology Corporation (MCC) is a cooperative research venture owned by US corporations. MCC's mission is to accelerate the creation, delivery, and commercialization of advanced microelectronic and computer technology by providing participants with timely and competitive research results. The author presents the unique history, operation, and research and technology transfer activities of the collaborative venture. The review of MCC's five research efforts focuses primarily on the computer-aided design, packaging/interconnect, and high-temperature superconductor programs. Selected research results are presented, and shareholder use of MCC technology in internal processes, as well as products, is discussed. Concluding remarks summarize MCC's accomplishments and continuing challenges  相似文献
