| Abstract | In this paper, the surface micro hole array photonic crystal structures were fabricated on p-type GaN of InGaN/GaN through photolithography and ICP dry etching process. We designed three different patterns of circle hole arrays, including square lattice array, triangle lattice array, and honeycomb lattice array. The hole diameter was around 6 mum, and the period of the lattice array was about 15 mum. There were two different depths in the lattice arrays, 1.1 mum and 100 nm. The increase in photoluminescence intensity of the InGaN/GaN multiple quantum wells with the square lattice array, triangle lattice array, and honeycomb lattice array structures have been 208%, 188%, and 90%, respectively. We found that the square lattice array structure induced the highest light extraction efficiency. |

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.
