Electric Black Holes in Type 0 String Theory

Abstract

We discuss AdS_{2+1} (BTZ) black holes arising in type 0 string theory corresponding to D1-D5 and F1-NS5 bound states. In particular we describe a new family of non-dilatonic solutions with only Dp_{+}, that is ``electric'' branes. These solutions are distinguished by the absence of fermions in the world volume theory which is an interacting CFT. They can not be obtained as a projection of a type II BPS-configuration. As for previous type 0 backgrounds linear stability is guaranteed only if the curvature is of the order of the string scale where alpha' corrections cannot be excluded. Some problems concerning the counting of states are discussed.
