| Laser | |
| Sapphire
is one of the most usable laser material in the form of the ruby (sapphire
with chromium addition) and titanium doped sapphire (with titanium
addition) due to: - transparency - ability to accommodate guest elements into crystal lattice other applications... |
|
| Semiconductors | |
| Sapphire
is an unique material for semiconductor substrates in some areas of
application: - radiation-resistant chips for space and nuclear power plant, - new high speed memory chips and high frequency chips (silicon - on - sapphire (SOI) chips) Sapphire is suitable material for these applications due to: - high dielectric constant - crystal lattice match with silicon. other applications... |
