Abstract: Disclosed herein are organic photosensitive devices including at least one exciton-blocking charge carrier filter. The filters comprise a mixture of at least one wide energy gap material and at least one electron or hole conducting material. As described herein, the novel filters simultaneously block excitons and conduct the desired charge carrier (electrons or holes).

Abstract: Methods of forming a stack without damaging underlying layers are discussed. The encapsulation layer and dielectric layer are highly conformal, have low etch rates, and good hermeticity. These films may be used to protect chalcogen materials in PCRAM devices or any substrates sensitive to oxygen or moisture. Some embodiments utilize a two-step process comprising a first ALD process to form an encapsulation layer and oxidation process to form a dielectric layer.

Abstract: Methods of depositing an encapsulation stack without damaging underlying layers are discussed. The encapsulation stacks are highly conformal, have low etch rates, low atomic oxygen concentrations, good hermeticity and good adhesion. These films may be used to protect chalcogen materials in PCRAM devices. Some embodiments utilize a two-step process comprising a first ALD process to form a protective layer and a second plasma ALD process to form an encapsulation layer.

Abstract: Chalcogen silane precursors are described. Methods for depositing a silicon nitride (SixNy) film on a substrate are described. The substrate is exposed to the chalcogen silane and a reactant to deposit the silicon nitride (SixNy) film. The exposures can be sequential or simultaneous. The chalcogen silane may be substantially free of halogen. The chalcogen may be selected from the group consisting of sulfur (S), selenium (Se), and tellurium (Te).
