Hierarchical Morphology Engineering of Silicon Micropillars Dictates Interfacial Kinetics for Room-Temperature Hydrogen Sensing

The precise construction of three-dimensional (3D) hierarchical architectures on silicon substrates is highly desirable for amplifying surface-dominated physicochemical interactions. However, traditional top-down microfabrication typically yields inherently smooth sidewalls, restricting active site density and causin...
