Growth of Urea Crystals by Physical Vapor Transport

摘要

This work demonstrates that high optical quality crystals of urea can be grown by the physical vapor transport method. The unique features of this method are compared with growth from the methanol/water solutions. High growth rates, exceeding 2.5 mm/day were achieved, and cm-size optical quality single crystals were obtained. Details of the growth technique and the physical properties of the crystals were obtained. Details of the growth technique and the physical properties of the crystals are presented.
