PREPARATION OF THIN CRYSTAL OR FILM

摘要

PURPOSE:To prepare efficiently pure crystal or film by providing mercury in the flat plate-like state in the inside of a housing regulated to the specified atmosphere, dropping liquid substance by which crystal or film is formed on the surface of mercury and thereby forming the thin crystal or film on the surface of mercury. CONSTITUTION:An aq. soln. of molecule making crystal is dropped on the surface of mercury 8 via a nozzle 10 from a feed source 9 of liquid substance. The aq. soln. dropped on mercury 8 is quickly developed on the surface of mercury and extremely thin film or crystal is made. As this time the water droplets of tip part of the nozzle 10 are touched to the surface of mercury by approaching the nozzle 10 to the surface of mercury 8. When DC voltage of about several volts is impressed between the nozzle and mercury 8 from a power source 11, the surface tension of the aq. soln. is decreased and the surface tension difference between mercury and the aq. soln. is made large and thereby the aq. soln. is instantaneously developed on the surface of mercury and extremely uniform from or crystal can be formed.
