Yb,jAs3 laas been known as a heavy ferttaion coznjcouzad xvith very low carriers. Recently,polarised netrtron ttaeastrrenaent has revealed the charge-ordered state in the loxv tenaperattrrephase after a strtrcttural phase transition. To clatri['y the conducting projcerty, a loand strttcttrre iscalcvxlated for hypotl'xetical LvrYb3As3 where Yl)" ?rre rep1?tced xvith Ltu, as it is 21 nonztazrgneticreference mstterial of' the claarge-ordered stsxte of' Ylc"Yb:"As3 . The restrlt shows LtrYb3As3to be a seuni-unetal with As-4p holes ?tnd Lvr-5d electrons, wlaich is consistent with the setaaiconducting behaviotur of the chtrrge-ordered state. Tlae Ferrni sttrfaces are located ova a planenornaal to the Yb" chain with q O 0.
