Research Activities

Saif Islam's nanotechnology research focuses on the incorporation of low-dimensional nanostructured materials and devices with conventional IC elements, employing processes compatible with mass-manufacturing. Unlike the research-based approach of sequentially connecting electrodes to individual nano-structures for device physics studies, massively parallel and manufacturable interfacing techniques are crucial for reproducible fabrication and incorporation of dense, low-cost nanodevice arrays in highly integrated material systems. He has developed two novel nano-device integration and mass-production techniques termed 'nano-bridges' and 'nano-colonnades' that are compatible with existing microelectronics fabrication processes. His group's (Inano) current research objectives include the development of massively parallel synthesis and integration processes for 0D and 1D nano-structures (semiconductors, metals, oxides, molecules) for potential applications in the areas of nanoscale electronics and photonics described in the Research Interest (above). A major focus of Inano is nanoepitaxy for homo and heterogeneous nanomaterial synthesis, characterization and device integration.

In order to manipulate the propagation of light, a study is underway on a new class of materials, called "negative index metamaterials (NIM)" that demonstrate unusual electric and magnetic properties not found in nature and offer opportunities for unprecedented functionalities in virtually every area of classical optics and photonics. His group is involved in developing new methods and tools for constructing 3D NIMs using manufacturable nanofabrication techniques and studying nano-structure integrated NIM based theoretical and experimental schemes. Besides device integration, the group is also actively involved in minimizing the losses that are inherent in NIM by exploring various thin film nucleation methods. The overall research activities in NIM are based on exploiting the synergy of nanoepitaxy for eventual monolithic realization of NIM enabled electronics and photonics.

Quantum electrodynamical (QED) phenomena lead to Casimir force which can be observed when metallic, semiconductor or dielectric surfaces are placed in close proximity (< 100 nm). This opens doors to exciting opportunities, particularly in the field of nanodevices and nanomechanics, such as nanoscale levitation, stiction prevention, and highly responsive sensors. Nanotechnology is capable of fabricating devices with diminishingly small dimension and this force cannot be disregarded any more. Inano studies this and other fundamental physical forces in nanoscale devices for improving old and creating new technologies.
