BixSb1-x solid solution single crystals growing by the Czochralski method with solid feed. These alloys have the original physical properties and the complex band edges. Therefore, BixSb1-x alloys are the best n-type materials for thermoelectric and magneto-thermoelectric cooling at temperature lower than 200 K and gradient crystals for short wave length X-rays and neutron beams. Also these materials have potential application in developing next-generation quantum computing devices.
Single crystals growth by Czochralski method
with solid feed
The influence of ultrasound with frequencies from 0.10 to 10 MHz on component distribution in InSb, GaAs, Ga1-xInxSb and BixSb1-x solid solution single crystals grown by the modified Czochralski method was studied. It was found that striations in single crystals pulled in the ultrasonic field are significantly reduced. The introduction of 3-MHz ultrasonic waves in Ga solution promoted best conditions for liquid-phase epitaxial growth of GaAs with a flat solid-liquid interface.
The crystal growth methods in ultrasonic field can be used for growing of homogeneous semiconductor single crystals with high electrophysical properties.
