SELF-ASSEMBLED NANOCHAMBER ARRAYS FOR in-situ TEM OBSERVATION OF LIQUID-PHASE SAMPLES

Abstract

This work presents a highly-ordered array of nanoscale chambers, capable of encapsulating liquid samples for TEM (transmission electron microscopy) imaging. The present nanochambers arc formed with two layers of free-standing graphene and self-assembled nanopores in an A AO (anodic aluminum oxide) membrane, which improve a transparency for electron beam and uniformities in chamber sizes/distributions. respectively. We envision that the present work will enable us to efficiently observe nanoscale processes in liquid with high-resolution TEM.
