| Abstract | Summary form only given. Integration of active III/V devices on Silicon substrates would tremendously increase the functionality of this semiconductor material. In order to realize true monolithic integration, a defect-free nucleation layer is of outmost importance. As CMOS industry nowadays focuses on exactly oriented (001) Si substrates, the integration of a III/V semiconductor based device structure, employing either lattice relaxed III/V layers for high electron mobility devices or the pseudomorphically strained, active direct-band gap material Ga(NAsP) for optic devices, also has to be pursued on this substrate type. High-efficiency, Si-based solar cells can however also be deposited on off-cut substrates. The III/V nucleation layer we use is GaP-based due to the similar lattice constants of GaP and Si. Besides the known challenges of III/V on IV heteroepitaxy, like charge neutrality of the interface, cross-diffusion of dopants and slight differences in lattice constant and thermal expansion coefficient, nucleation on Si furthermore poses the challenge of the formation of antiphase domains. These form as the Si surface is covered with monoatomar steps. This presentation will summarize our current knowledge on the nucleation of III/V semiconductors on Silicon substrates. A specific focus will be on the avoidance of defects as well as on the atomic structure of the GaP/Si interface. Moreover, we will address the successful pseudomorphic integration of a Ga(NAsP)-based laser on this template. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
