Abstract Two-dimensional materials (2DMs) have been used widely in constructing
photodetectors (PDs) because of their advantages in flexible integration and ultrabroad …

The discovery of the photoelectric effect by Heinrich Hertz in 1887 set the foundation for over
125 years of hot carrier science and technology. In the early 1900s it played a critical role in …

Nanoscale localization of electromagnetic fields near metallic nanostructures underpins the
fundamentals and applications of plasmonics. The unavoidable energy loss from plasmon …

Nanoantennas are key optical components for light harvesting; photodiodes convert light
into a current of electrons for photodetection. We show that these two distinct, independent …

Graphene (Gr) has many unique properties including gapless band structure, ultrafast
carrier dynamics, high carrier mobility, and flexibility, making it appealing for ultrafast …

We investigate theoretically the effects of generation and injection of plasmonic carriers from
an optically excited metal nanocrystal to a semiconductor contact or to surface molecules …

Planar metal–oxide–metal structures can serve as photodetectors that do not rely on the
usual electron–hole pair generation in a semiconductor. Instead, absorbed light in one of the …

When plasmonic nanostructures serve as the metallic counterpart of a metal–semiconductor
Schottky interface, hot electrons due to plasmon decay are emitted across the Schottky …

The paper reviews physical concepts related to the collective dynamics of plasmon
excitations in metal nanocrystals with a focus on the photogeneration of energetic carriers …

Finding alternative optoelectronic mechanisms that overcome the limitations of conventional
semiconductor devices is paramount for detecting and harvesting low-energy photons. A …
