Optimization of Thermal Stresses During Czochralski Growth of Oxides and Halides
A parametric optimization of the hotzone geometry for Czochralski growth is conducted to minimize thermal stress in a validated CsI furnace model. The optimal design, incorporating a heat shield, top susceptor, and modified induction coil, reduces crystal stress by a factor of 3.7.

Anomalous optical surface absorption in nominally pure silicon samples at 1550 nm [PDF]
The announcement of the direct detection of Gravitational Waves (GW) by the LIGO and Virgo collaboration in February 2016 has removed any uncertainty around the possibility of GW astronomy. It has demonstrated that future detectors with sensitivities ten
