Journal ArticleDOI
Particle generation and film formation in an atmospheric-pressure chemical vapour deposition process using tetraethylorthosilicate
TL;DR: In this paper, the effects of an oxygen flow rate on film formation and nanometre-sized particle generation in the gas phase were examined simultaneously in an atmospheric-pressure chemical vapour deposition reactor using tetraethylorthosilicate (TEOS).
Journal ArticleDOI
Electrical neutralization of charged aerosol particles by bipolar ions.
TL;DR: In this article, the minimum concentration of bipolar ions required to neutralize the charged particles under various conditions was estimated using dimensionless parameters, and the necessary conditions for charged particles to attain equilibrium charge distributions were clarified.
Journal ArticleDOI
Aerosol formation by rapid nucleation during the preparation of SiO2 thin films from SiCl4 and O2 gases by CVD process
TL;DR: In this paper, the formation of aerosol particles and molecular clusters by rapid nucleation in the semi-conductor thin-film preparation process by APCVD or low pressure chemical vapor deposition (LPCVD) is evaluated by a vapor nucleation and diffusion model.
Journal ArticleDOI
Formation of Fine Particles of Zinc Sulfide from Thiourea Complexes by Spray Pyrolysis
TL;DR: In this article, fine particles of ZnS were obtained by ultrasonic spray pyrolysis of an aqueous solution containing Zn(NO3)2 and SC(NH2)2 in appropriate molar ratios, the carrier gas being N2.
