A determination of the steady state nucleation rate r n in thermally annealed a-Si:H has typically been performed using TEM, where the increase in grain density with isothermal sample anneal time can be directly observed for samples with small crysta

Utilizing the concepts of a critical crystallite size and local film inhomogeneity, it is shown that nucleation in thermally annealed hydrogenated amorphous silicon occurs in the more well ordered spatial regions in the network, which are defined by

Hot-wire chemical vapor deposition (HWCVD) has been employed as an economically scalable method for the deposition of crystalline molybdenum oxide nanoparticles at high density. Under optimal synthesis conditions, only crystalline nanostructures with

Our research aiming to improve silicon photovoltaic materials and devices extensively utilizes hot-wire chemical vapor deposition (HWCVD). We have recently achieved 18.2% heterojunction silicon solar cells by applying HWCVD a-Si:H front and back cont

Electrochromic (EC) materials change their optical properties (darken/lighten) in the presence of a small electric potential difference, and are suitable for application in energy-efficient windows, antiglare automobile rear-view mirrors, sunroofs, d

Hot wire chemical vapor deposition (HWCVD) has been adapted to be a continuous growth process for high-density carbon multiwall nanotubes (MWNTs). MWNT growth is optimized in 1:5 CH4:Ar at 150 Torr with reactor temperatures of 400 and 550 °C for sta

We observe that the charge state of diffusing hydrogen depends upon the electronic Fermi level ( E f ) in hydrogenated amorphous silicon (a-Si:H). We incorporate a thin layer of deuterium ( 2 H) at various positions between the n- and p-layers of i
