Abstract

Permeation barrier films are critical to a wide range of applications ranging from food and medical packaging to organic electronics and photovoltaics. For some of these applications, not only low permeation values are required but also flexible and transparent. Here, I will present synergistic chemical vapor deposition (CVD) and atomic layer deposition (ALD) processes for scalable manufacturing of few-layer graphene/alumina-based nanolaminates. The resulting ~10 nm thick contiguous film provides an effective encapsulation for organic light-emitting diodes (OLEDs) with measured half-life times of 880 h in ambient.
