Singh Center for Nanotechnology

Singh Center for Nanotechnology. It is a premier interdisciplinary research facility at the University of Pennsylvania dedicated to advancing the science and engineering of nanoscale systems. The center provides state-of-the-art fabrication and characterization tools to researchers from Penn Engineering, the Penn Arts & Sciences, and external partners from industry and academia. Its mission is to foster innovation in fields such as nanomedicine, quantum computing, and advanced materials through collaborative research and education.

History and establishment

The center was made possible by a landmark gift from Krishna P. Singh, an alumnus of the University of Pennsylvania and founder of Holtec International. This philanthropic commitment, announced in 2010, was one of the largest single donations in the university's history and was specifically earmarked for advancing nanotechnology research. The facility was designed by the architectural firm Weiss/Manfredi and officially opened its doors in the fall of 2013. Its establishment consolidated previously dispersed nanofabrication and characterization resources at the university, creating a centralized hub that significantly enhanced Penn's competitive position in the global nanoscience landscape.

Facilities and capabilities

The center houses over 10,000 square feet of Class 100 cleanroom space, featuring advanced tools for electron-beam lithography, atomic layer deposition, and reactive-ion etching. Key instrumentation includes a Zeiss field emission scanning electron microscope and a suite of optical lithography systems for patterning at the micro- and nanoscale. The Quattrone Nanofabrication Facility forms the operational core, providing open-access resources to trained users. Supporting laboratories are equipped for molecular beam epitaxy, scanning probe microscopy, and Raman spectroscopy, enabling comprehensive analysis of materials from the atomic to the macroscopic level.

Research and academic programs

Research thrusts are highly interdisciplinary, bridging electrical engineering, materials science, physics, chemistry, and bioengineering. Major initiatives include developing nanophotonic devices for next-generation optical computing, engineering two-dimensional materials like graphene for flexible electronics, and creating targeted drug delivery systems. The center is integral to the University of Pennsylvania's graduate programs, offering specialized courses and hands-on training through the Nanotechnology Master's Program. It also hosts the National Nanotechnology Coordinated Infrastructure (NNCI) site, providing access and expertise to researchers from across the United States.

Leadership and organization

The center is led by its faculty director, currently Mark G. Allen, the Alfred Fitler Moore Professor in Electrical and Systems Engineering. Strategic oversight is provided by a faculty executive committee with representatives from key departments including the Department of Materials Science and Engineering and the Department of Physics and Astronomy. Day-to-day operations of the core facilities are managed by a team of professional staff scientists and engineers. The center maintains strong collaborative ties with other Penn institutes, such as the Penn Center for Energy Innovation and the Institute for Medicine and Engineering.

Significance and impact

The Singh Center has established the University of Pennsylvania as a leader in nanotechnology, attracting top-tier faculty and significant research funding from agencies like the National Science Foundation and the Department of Defense. Its open-access model has catalyzed breakthroughs, leading to high-profile publications in journals like *Science* and *Nature* and the formation of numerous startup companies. By training the next generation of scientists and engineers and providing critical infrastructure to the broader research community, the center plays a pivotal role in translating fundamental nanoscience into technological innovations that address global challenges in healthcare, energy, and information technology.
