Doped metal oxide (MO) nanocrystals (NCs) are well-known for the localized surface plasmon resonance in the infrared range generated by free electrons in the conduction band of the material . Owing to the intimate connection between plasmonic features and t h e NC's carrier density profile, proper modeling can unveil the underlying electronic...

Doped metal oxide nanocrystals are emerging as versatile multi-functional materials with the potential to address several limitations of the current light-driven energy storage technology due to their unique ability to accumulate a large number of free electrons upon UV light exposure. The combination of these nanocrystals with properly...

Nowadays materials to protect equipment from unwanted multispectral electromagnetic waves are needed in a broad range of applications including electronics, medical, military and aerospace. However, the shielding materials currently in use are bulky and work effectively only in a limited frequency range. Therefore, nanostructured materials are...

In this work, we observe plasmon-induced hot electron extraction in a heterojunction between indium tin oxide nanocrystals and monolayer molybdenum disulfide. We study the sample with ultrafast differential transmission, exciting the sample at 1750 nm where the intense localized plasmon surface resonance of the indium tin oxide nanocrystals is...

Absorbing near-infrared (NIR) photons, with longer wavelengths, in atomically thin monolayer MoS2 presents a significant challenge due to its weak optical absorption and narrow absorption bands. Consequently, MoS2-based photodetector devices often experience low responsivity and a limited detection window. Herein, a novel InAs@ZnSe...
