Clay Electronics: Hetreo-junction Formation of Inorganic Nanosheets

Abstract

Recently the exfoliated ultrathin sheets from layered inorganic materials have attracted an extensive attention because of their application to thin film-type electronic devices and sensors. Among a variety of layered inorganic compounds, smectite clay minerals are a unique candidate because of their abundance in nature and kindness for environment. For these purposes, we have prepared a cast film of exfoliated clay and studied its electronic conduction through the hetero-interface.
