Growth of mercuric iodide single crystals by physical vapor transport: development of a new 'monothermal' furnace Non-destructive bulk characterization by a laboratory Hard X-ray method

摘要

A new growth device in vapour phase to obtain large iodide mercuric single crystals is presented here. The temperature field of this furnace is better defined than in the devices derived from the Scholz process. Using a volume diffraction method recently developed at the "Institute Laue Langevin", we compare the crystalline quality of two crystals produced in our device and in a Scholz type furnace.
