Atomic force microscopy-based infrared spectroscopy (AFM-IR) is a rapidly emerging
technique that provides chemical analysis and compositional mapping with spatial …

Hierarchical materials that exhibit order over multiple length scales are ubiquitous in nature.
Because hierarchy gives rise to unique properties and functions, many have sought …

It is highly desirable to discover photovoltaic mechanisms that enable enhanced efficiency of
solar cells. Here we report that the bulk photovoltaic effect, which is free from the …

This review discusses a relatively new technique for optical nanoimaging at visible
wavelength, known as tip-enhanced Raman spectroscopy (TERS). This technique relies on …

This review describes the growing partnership between super-resolution imaging and
plasmonics, by describing the various ways in which the two topics mutually benefit one …

In this feature article, we discuss in detail developmental bottleneck issues in Raman
spectroscopy in its early stages and surface-enhanced Raman spectroscopy (SERS) in the …

Almost 100 years after the discovery of the Raman scattering phenomenon, related
analytical techniques have emerged as important tools in biomedical sciences. Raman …

On-surface synthesis is the bottom-up construction of covalent bonds between molecular
building blocks, which has been greatly developed during the past decade. Dozens of …

Unambiguous chemical identification of individual molecules closely packed on a surface
can offer the possibility to address single chemical species and monitor their behaviour at …

Abstract 2D materials and heterostructures have attracted significant attention for a variety of
nanoelectronic and optoelectronic applications. At the atomically thin limit, the material …
