In the year 2001 leading Russian specialists from the NII «Giredmet», «Kvant», JSC «ELMA», working in the fields of non-ferrous, rare, precious metals and semi-conductor materials, united their efforts and founded the scientific-technological association – the «ADV-Engineering» LLC.
The principal directions of work of our Company are:
-engineering services;
-production of high purity metals and semi-conductor materials of the AIIBVI group;
-production of thermoelectric materials and modules in cooling and generating fields;
-patent – legal activities.
The «ADV-Engineering» LLC has its own production capacities in the city of Zelenograd (Russia), which allows to react efficiently to the demands of the client, pertaining to the quality and technical characteristics of the materials, produced by our firm. Technological and constructive solutions worked out in our Company are protected by Russian patents.
Highly qualified scientists and specialists are working for the «ADV-Engineering» LLC: 2 Doctors of technological sciences, 5 Candidates of technological sciences, 2 research fellows are studying at post-graduate courses.
The strategic target of the Company is to broaden the existing and to create new highly effective productions in Russia. The pricing policy of the «ADV-Engineering» LLC is aimed at supporting long-standing relations with its partners and envisages a system of discounts. Our Company, the «ADV-Engineering» LLC , is open for mutually beneficial co-operation.
Semiconductor materials of the АIIBVI group
АДV-Engineering: Semiconductor materials of the АIIBVIgroup: СdS(5N), СdTe(5N), ZnS-Ag, ZnSe-Ag, CdSe, ZnS, ZnSe, ZnTeThe use of monocrystals ZnS, CdS, CdSe, ZnSe, ZnTe, CdTe in photoresistors, photoelements, infrared viewers, semiconductor detectors and lasers is connected with their optical properties and photosensitivity.
Some semiconductor materials have the ability to transform different types of energy into light and luminiscent, i.e., to emit light with waves of various lengths. Luminophores are used in the production of chromatic kinescopes: ZnS-Ag emits a blue colour, ZnSe-Ag shines green. (Zn,Cd)S-Ag are used in X-ray tubes, while ZnS-Cu works in the indicator boards and panels. At present compounds of CdS и CdTe are used in solar applications.
Due to the high demands for purity and perfection of the structure of semiconductor materials, the technology of their production, high stability of technological performance, the “ADV-Engineering” Co., Ltd. ensures the output of high purity semiconductor materials, needed for growing monocrystals.
Our company has technologies for the production of CdSe, ZnS, ZnSe, ZnTe powders and in the presence of stable markets is ready to expand their production.
The following polycrystalline powders are produced:
-СdS(5N)
-СdTe(5N)
Cadmium telluride (CdTe) of high purity in the form of polycrystalline ingots with diameter 45 mm and targets with diameter 45 mm and thickness ≥6mm.
