GaAs Semiconductor Crystal Structure Model
SKU: 68762W
This 146 atom model kit shows the FCC structure of AlGaAs (aluminum gallium arsenide), a III-V compound semiconductor with tetrahedral cooridination that is used in infrared emitting diodes. The AlGaAs & GaAs (gallium arsenide) face-centered cubic crystal structure is similar to zinc blende.
Their lattice constants vary depending on the proportion of aluminum (Al) and gallium (Ga) in the compound. The chemical formula can be written as AlxGa1−xAs where x is the aluminum fraction and ranges from 0 in pure GaAs to 1 in pure AlAs.
Indigo Instruments has maintained a substantial inventory of genuine Cochranes of Oxford (Orbit) parts for 30+ years (scroll down to see "Skeletal (Orbit/Minit) and are compatible with every molecular model kit we have sold since day 1. This level of quality may appear expensive but no parts support from other vendors costs even more.
