Resumen
The growth of InP single crystals by liquid encapsulated Czochralski (LEC) is usually performed using quartz or pyrolitic boron nitride crucibles. However, both these crucibles pose some problems which have resulted in their limited use. An alternative method has been proposed which uses a high pressure puller and glassy-carbon crucibles, undoped InP single crystals weighing 100 g and with 25 mm diameter. The residual carrier concentration of the samples were as good as those obtained with quartz crucibles with the advantage that glassy-carbon crucibles are fully reusable.
