Creation of arbitrary features with high resolution is critically important in the fabrication nano-optoelectronic devices. Here, sub-50 nm surface structuring achieved directly on Sb2S3 thin films via microsphere femtosecond laser irradiation far field. By varying fluence and scanning speed, nano-feature sizes can be flexibly tuned. Such small patterns are attributed to c...

We describe a conductance-based biosensor that exploits DNA-mediated long-range electron transport for the label-free and direct electrical detection of DNA hybridization. This biosensor platform comprises an array of vertical nano-gap biosensors made of gold and fabricated through standard photolithography combined with focused ion beam lithography. The nano-gap walls are covalently modified w...

The unabated silicon technology scaling makes design and manufacturing increasingly harder in nanometer VLSI. On one hand, major design objectives such as timing, power, and noise are often conflicting with each other in modern designs with multi-million gates, resulting in complex design closure. On the other hand, design closure no longer guarantees historical yield norm, requiring ever-chall...
