Lead Selenide Nanostructures Self-Assembled across Multiple Length Scales and Dimensions

Abstract EN

A self-assembly approach to lead selenide (PbSe) structures that have organized across multiple length scales and multiple dimensions has been achieved.

These structures consist of angstrom-scale 0D PbSe crystals, synthesized via a hot solution process, which have stacked into 1D nanorods via aligned dipoles.

These 1D nanorods have arranged into nanoscale 2D sheets via directional short-ranged attraction.

The nanoscale 2D sheets then further aligned into larger 2D microscale planes.

In this study, the authors have characterized the PbSe structures via normal and cryo-TEM and EDX showing that this multiscale multidimensional self-assembled alignment is not due to drying effects.

These PbSe structures hold promise for applications in advanced materials—particularly electronic technologies, where alignment can aid in device performance.
