“…The substitution in the WS 2 lattice can take place both in the cation and in the anion sub-lattice. WCh 2 mixed phases (Ch: S, Se): (a) [166,169,177,184,185] On (a): For the crystal growth of WS 2-x Se x mixed phases the chemical transport with iodine is described and also the sublimation of this mixed phase (direct vapor transport). [169] W 1-x M x Ch 2 mixed phases (M = Mo, Ch: S, Se): (a) [110,116,135,150,152,165,186] On (a): The formation of the following mixed phases is described in the literature: W 1-x Mo x S 2 , [110,116,150] W 1-x Mo x Se 2 , [135,152] W 1-x Re x S 2 , [165] W 1-x Re x Se 2 [186] and W 1-x Nb x S 2 .…”
