摘要：
Bi-Sb single crystals with a well defined slope of composition have been grown by the gradient projection method (GPM). The gradient crystals obtained exhibit a lattice parameter gradient of Delta a/(a) over bar/dz = 0.835%/cm and Delta c/(c) over bar/dz = 0.79%/cm. The concentration profiles of the grown crystals show a good approximation to a linear distribution, By adjusting the growth rate and using a single crystalline seed the quality of the grown crystals could be drastically increased, (C) 1999 Elsevier Science B.V.
