Similarly , bipolarons with a

antikink ) smaller than about 6 - 7 lattice constants are unstable . If

larger distance , bipolarons can exist , but with a small binding energy of the

order kt .

Similarly , bipolarons with a

**separation**distance of the two charges ( kink -antikink ) smaller than about 6 - 7 lattice constants are unstable . If

**separated**by alarger distance , bipolarons can exist , but with a small binding energy of the

order kt .
