About Our Technology
The use of the II-VI compounds has been slow to develop
because there has not been a source of high quality material in consistent, high volume supply. The material on the market has a high incident of crystalline imperfection. The crystal lattice is full of inclusions of tellurium, linage,
subgrain structure and lattice dislocations. Until a source of high quality wafers can be developed, little increase in the use of II-VI compounds is anticipated.
One problem inhibiting the development of devices which use II-VI
semiconductor material is the extremely high cost of this material. It is important to know that all of the II and VI elements used for the production of semiconductors are abundantly available and are easily purified. The major barrier to
reduced cost and improved supply is therefore in the economics and quality of the processing methods. As a result with improved processing methods the use of the II-VI compounds will increase, the cost of elements will decrease and this
will allow II-VI materials to potentially compete with gallium arsenide and indium phosphide in price structure.
