	Dichroic behaviors of layered ReS<sub>2</sub> have been characterized using angular dependent polarizedabsorption and resistivity measurements in the van der Waal plane. The angular dependent optical and electrical measurements are carried out with angles ranging from <i><span style=\"font-family:'Times New Roman','serif';font-size:10pt;\">¦È</span></i><span style=\"font-family:'Times New Roman','serif';font-size:10pt;\"></span><span style=\"font-family:'Times New Roman','serif';font-size:10pt;\"></span><span style=\"font-family:'Times New Roman','serif';font-size:10pt;\"></span><span style=\"font-family:'Times New Roman','serif';font-size:10pt;\"></span><span style=\"font-family:'Times New Roman','serif';font-size:10pt;\"></span><span style=\"font-family:'Times New Roman','serif';font-size:10pt;\"></span><span style=\"font-family:'Times New Roman','serif';font-size:10pt;\"></span>= 0<span style=\"font-family:'Times New Roman','serif';font-size:10pt;\"><span style=\"font-size:10.5pt;font-family:ËÎÌå;\">¡ã</span></span>(E || <i><strong>b</strong></i>) to <i><span style=\"font-family:'Times New Roman','serif';font-size:10pt;\">¦È</span></i>= 90<span style=\"font-family:'Times New Roman','serif';font-size:10pt;\"><span style=\"font-size:10.5pt;font-family:ËÎÌå;\">¡ã</span></span>(E ^<i><strong>b</strong></i>) with respect to the layer crystal¡¯s <i><strong>b</strong></i>-axis.
