Fundamental Scientific Research


Nanophotonics is a fast-developing research area over the past two decades. With advanced nanopatterning and nanofabrication techniques, specially designed nanostructures with deep sub-wavelength dimensions have enabled the demonstrations of negative-refractive-index materials, metamaterials, plasmonic sensing, metalenses and metasurfaces, etc.

The fabrication of nanophotonic structures is complex, costly, and often time-consuming, especially when mass production for practical applications is concerned. InterLitho’s team has extensive experience in patterning and fabricating various nanophotonic devices that contain uniform or spatially varying gratings, pillars, and holes in noble metals and dielectrics for a wide range of applications of optical filters, surface-enhanced Raman or fluorescence sensing, polarization converters, etc. Our expertise in nanophotonic fabrication and device design will help our customers in both scientific research and product development.

2D Materials

Atomically thin 2D materials, such as graphene, MoS2, h-BN, black phosphorus, just to name a few, is a large family of new materials with intriguing electronic, mechanical, chemical, and optical properties that open fascinating opportunities in both scientific research and device integration. Nanopatterning and nanofabrication are essential in exploring 2D materials’ fundamental science and engineering them in sensors, memories, transistors, etc. InterLitho’s team works on applying our nanofabrication expertise into this fast-growing area through collaboration with expert scientists in this field. 

Perovskite Optoelectronics

Perovskite is a series of material with a crystal structure following the formula ABX3. Halide perovskite materials possess fascinating physical properties such as long photocarrier diffusion lengths and large absorption coefficients that give perovskite solar cells (PSCs) excellent performance. Halide perovskite materials also perform well in other photovoltaic applications such as light emitting diodes, photodetectors, and X-ray scintillation. Our lithographic patterning and fabrication processes have been applied to developing innovative patterned peroskite photodetectors and displays that incorporate nanostructured interfaces fabricated by nanoimprint or pixelated patterns deposited by ultrafine metal masks.
