Demand on high quality amorphous hydrogenated Si (a- Si:H) for thin film solar cell or microelectronics applications necessitates microscopic and in-situ access to various processes in this fundamentally interesting material. We demonstrate that such access can be provided by combining first principles computational simulations with commonly used infrared vibrational spectroscopy and still rarely...
Hydrogenated amorphous silicon (a-Si:H) has been the subject of considerable studies in the past 30 years, due to its growing application in large area optoelectronic devices, and especially in solar cells (see, for instance). In particular, the microscopic details of disordering, hydrogen migration and bonding within the amorphous silicon network are crucial for the understanding of a-Si:H, including...
