Photodetectors with blackbody response show significant applications in remote sensing and infrared imaging. However, up to now, few works have demonstrated excellent response to blackbody radiation (weak irregular radiation from a real object), which is essential to reliably evaluate their potential in practical detections. Researchers now have demonstrated van der Waals unipolar barrier photodetectors with nBn and pBp heterostructures. Designing unipolar barriers with conventional ...

The modification of surface properties, such as metals, medical devices, and glass mirrors, represents a vital opportunity to inhibit the buildup of proteins or contaminants (i.e., fouling) for biomedical materials/devices, food packaging, many membrane filtration applications. Surface coatings with sustainable anti-fouling, bactericidal or the killing of bacterial membrane cells, and self-cleaning surface properties are particularly desirable and are receiving great attentions. ...
