The Bridgman technique emerges as an indispensable innovation in the realm of crystal growth, embodying precision and excellence in the formation of single crystals. Developed by the pioneering physicist Percy Williams Bridgman, this methodology stands out for its unique simultaneous bi-directional control, orchestrating both the transition and rotation movements of the seed holding rod. This dual control ensures a flawlessly executed crystal growth process, minimizing imperfections and enhancing the overall quality of the resulting single crystal. The meticulous temperature control and management of the solidification front further contribute to the uniformity and integrity of the crystal structure. Widely applicable across industries, from semiconductor manufacturing to materials science research and optoelectronics, the Bridgman technique is celebrated for its versatility. Its implementation through modern crystal growth pullers and control units ensures precision, consistency, and reliability in the creation of high-purity, flawless single crystals. As a cornerstone technology, the Bridgman technique continues to drive advancements, offering a transformative approach to crystal growth with far-reaching implications for materials science and technology.
