This paper addresses the chiral structures of triglycine sulfate (TGS) crystals resulting from doping it with alanine. The alanine-doped TGS (ATGS) crystals were grown in an aqueous solution by the slow evaporation method at 293 K. The doping ratios of alanine in these crystals were calculated using intensity data of circular dichroism measurements and the ferroelectric domains were precisely investigated by the decoration method with positively charged carbon powder. Single-domain state was observed when the doping ratio was over 0.5 mol%. It was discussed that the chiral preference in ATGS crystals was attributed to the internal bias electric field generated by doping it with alanine.
