Large size hexagonal phase GaTe (Gallium luride) crystals have been developed at our facilities using three different growth techniques, namely Bridgman growth, chemical vapor transport (CVT), and flux zone growth, to optimize grain sizes and reduce defect concentrations. In contrast to commonly used chemical vapor transport (CVT) technique, flux grown crystals are well known for their structural perfection and electronic/optical performance. Bridgman and flux zone methods both offer similar grade qualities. Each crystal very large in size to last for years, is highly crystalline, oriented in 0001 direction, and easy to exfoliate. Our R&D staff takes characterization dataset in each sample piece to ensure structural, optical, and electronic consistency.
