have another question regarding the SCISSOR_OPERATOR. When I think,
this is used to match the band gaps when we have a smaller theoretical
value than the experimental one. If anyone have some idea, please let me
know whether it is a must for any semiconductor (metal oxide)?</div><div dir="ltr" id="yui_3_16_0_ym19_1_1505882981741_5877"><br id="yui_3_16_0_ym19_1_1505882981741_5878"></div><div dir="ltr" id="yui_3_16_0_ym19_1_1505882981741_5879">For
