Amorphous silicon - Wikipedia
Amorphous silicon (a-Si) is the non-crystalline form of silicon used for solar cells and thin-film transistors in LCDs. Used as semiconductor material for a-Si solar cells, or thin-film silicon solar cells, it is deposited in thin films onto a variety of flexible substrates, such as glass, metal and plastic. Amorphous silicon cells generally ...
The Local Structure of Amorphous Silicon | Science - AAAS
Feb 24, 2012 · Amorphous silicon (a-Si) can be regarded as a classic example of a disordered four-coordinated covalent material. Understanding its structure has implications for understanding structures and structure-properties correlations not only for similar covalently bonded networks but also for a wider range of other amorphous materials.
Realistic Atomistic Structure of Amorphous Silicon from Machine ...
May 12, 2018 · Amorphous silicon (a-Si) is a widely studied noncrystalline material, and yet the subtle details of its atomistic structure are still unclear. Here, we show that accurate structural models of a -Si can be obtained using a machine-learning-based interatomic potential.
While crystalline silicon FET’s are the key enablers for the integrated circuit field, amorphous silicon thin film transistors are the key semiconductor of the large-area electronics field, also known as “macroelectronics.” This talk reviews the basic properties of …
To understand the structure of an amorphous material, the atomic scale order, or short-range order (SRO) characteristics, need to be thoroughly investigated.
The structure of amorphous silicon has attracted particular interest over the recent decades [11–15] as it has been regarded as a model system of a covalently bonded CRN. The nature of the strong covalent Si-Si bonding does not allow for large deviations from the mean bond-length or bond-angle and its monatomic nature simplifies theoretical con-
amorphous silicon solar cells are realized in practice, and we then briefly summarize some important aspects of their electrical characteristics. 12.1.2 Designs for Amorphous Silicon Solar Cells: A Guided Tour
Amorphous Silicon - an overview | ScienceDirect Topics
Amorphous silicon is a non-crystalline form of silicon with disordered silicon atoms, known for its high light absorptivity. It is used in thin-film PV cells due to its lower production costs and the ability to be deposited on various substrates like steel, glass, and plastic.
