China in the Crystal Research, Institute of Physics so Dr. Chen Xiaolong's team leader, silicon carbide crystals is developed by the Institute of Physics of seven years, the state invested 17 million R & D success, with a number of national patents, in addition to both foreign patents, Institute of Physics The main products are two inches piece Yue Crystal Materials Co., Ltd. Shandong days, which is mainly used 6H luminescent substrate body. Shandong days Yue Crystal Materials Co., 4H for semiconductor applications, successfully developed in 2003, 2006 has been designed and manufacture with independent intellectual property rights of SiC crystal growth furnaces, technical and laboratory production has been completely successful, and has been successfully sold abroad, in cooperation with the energy resources of Tianfu Thermoelectric is the perfect combination of research institutes and enterprises, domestic carbonation Silicon wafers study represents the main State Key Laboratory of Crystal Materials, Shandong University and the Institute of Physics. Market Analysis: As the SiC crystal growth is difficult, resulting in SiC crystal growth of industrialization has been slow. After decades of research and development on a global scale has only a small number of research institutes and several semiconductor companies to master the technology. In addition to the current domestic Tianfu Thermoelectric no company can be produced, mainly the United States Cree foreign companies, the company's 2001 sales of SiC and related products reached $ 180 million, a profit of $ 48 million. 1997-2001 Cree five years the company's sales with an average annual growth rate of 58%. Silicon carbide crystals for a variety of electronic components substrate, the current international market is 2 inches in diameter (radius 25mm × 0.3mm) of the SiC crystal substrate is priced at $ 500-800 / slice. It is estimated that in 2005 only turnover SiC semiconductor market will reach 200 million $ 50 million internationally. By 2009, due to demand for SiC and GaN semiconductor devices, high-brightness blue LED and ultraviolet LD, and solid-state lighting, and broadband semiconductors (SiC, GaN) market volume will increase to $ 4.8 billion. Furthermore Shandong days Yue production and development of silicon carbide, SiC power devices in high-frequency devices such as power conditioning and communications systems, and high-definition television system immeasurable market prospects. Piezoelectric crystal when the crystal by external force, the crystal will polarization occurs, and the formation of surface charge, a phenomenon known as direct piezoelectric effect; the other hand, when the crystal is subjected to external electric field, the crystal will be deformed, a phenomenon known as an inverse piezoelectric effect. Crystals have piezoelectric effect are called piezoelectric crystals, it only exists in the center of symmetry of the crystal is no class. First discovered the piezoelectric crystal is a crystal (α- SiO2). It has a stable frequency characteristic, is an ideal piezoelectric material used to make resonators, filters, transducers, optical deflector, the surface acoustic wave device and a variety of thermal, gas, and chemical sensitization of the photosensitive devices. It is widely used in people's daily lives, such as quartz watches, digital clock, color TV, stereo radio and tape recorders. In recent years, there has developed a number of new piezoelectric crystal, such as lithium niobate perovskite type structure (LiNbO3), potassium tantalate (KTaO3), etc., sodium niobate, barium tungsten bronze-type structure (Ba2NaNb5O15), niobium potassium lithium (K1 - xLiNbO3) and the like layered structure BGO (Bi 12GeO20) and the like. To the piezoelectric effect of these crystals can be made into a variety of devices, widely used in military and civil industry, such as blood pressure, respiration measuring heart sounds, piezoelectric keyboards, delay line, an oscillator, an amplifier, a piezoelectric pump, ultrasonic transducer, a piezoelectric transformer.
