Scalable microfabrication technology has enabled semiconductor and microelectronics industries, among other fields.Meanwhile, rapid sensitive bio-molecule detection is increasingly important for drug discovery biomedical diagnostics.In this work, we designed demonstrated that photonic crystal sensor chips have high sensitivity protein can be mass-produced with scalable deep-UV lithography.We label-free of carcinoembryonic antigen from pg/mL to μg/mL, quality factor nanobeam cavities.
Silicon-organic solar cells based on conjugated polymers such as poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PSS) n-type silicon (n-Si) attract wide interest because of their potential for cost-effectiveness and high-efficiency. However, a lower barrier height (Φb) shallow built in (Vbi) Schottky junction between n-Si andPSS hinders the power conversion efficiency (PCE) comparison with those traditional p-n junction. Here, strong inversion layer was formed surface by inserting...
