The Bridgman method of (BiAs)2 (TeSe)3 bulk single crystal growth by spontaneous nucleation

The Bi0.5As1.5Te2.98Se0.02 single crystal in 11 mm?80 mm size was grown using the Bridgman method. Energy dispersive spectrometry (EDS) analysis used to determine chemical composition of studied samples, as well for checking and confirming homogeneity samples. Mobility, concentration charge majority carriers Hall coefficient crystal, were determined a Effec system based on Van der Pauw Effect measured at room temperature with four ohmic contacts liquid nitrogen silver an applied magnetic field strength 0.37 T different current intensities. expected improvement mobility obtained doped this content arsenic not obtained.
