Abstract
In a covered graphite slider apparatus for the liquid phase epitaxial growth of mercury cadmium telluride, this invention shows the addition of an improved wipe-off arrangement positioned in tandem with the CdTe substrate upon which the HgCdTe epitaxial layer is grown. This arrangement includes the providing of a discardable CdTe drainage apron adjacent the substrate for preventing residual growth solution from migrating back onto the substrate which has just been wiped-off by the LPE slider.
