Interests:
Czochralski
(CZ) and Bridgman
techniques are used to investigate some aspects in the crystal growth
of Nd:YAG,
PMN-PT,
TeO2, ZnO-TeO2, and CdO-TeO2 systems.
The
successful growth of Zn2Te3O8 and ZnTeO3
was performed for the first time. Optical, electrical,
and
structural studies on the grown crystals were performed. The glass form
of ZnO-TeO2 system was intensively studied, and some
electrical and optical properties were determined.
|
A new compound/phase in the ZnO-TeO2 system was discovered using powder and single crystal X-ray diffraction. The crystal structure and several important physical properties of this new compound have been identified. Simulation of the new compound and other X-ray results were done by CrystalDiffract and CrystalMaker computer software. |
Side
Projects:
- The
design and the making of a weighing system to
measure the
mass of the growing crystal during CZ growths. The weighing system was
automated to control the growth using LabView.
- The
exothermic reaction of selenium, germanium,
and
tellurium mixture at high temperatures was also studied.
- Experimental equipment design/development, particle synthesis, and a wide range of analytical testing techniques. Powder handling and processing e.g. safety, milling, and consolidation. X-ray analysis, non destructive measurements, and crystal growth.
I was born in Amman-Jordan where I went to a public high school. Then I joined the University of Jordan-department of physics, where I finished my B.Sc in physics in 1993, then my M.Sc. in condenssed matter solid state physics in 1997. During the time I was doing my Masters, I was a high school teacher of physics. In 1999 I was accepted in the physics program at
