PHYSICS RESEARCH CENTRE

CRYSTAL GROWTH CENTRE

In-charge: Dr. P.SELVARAJAN  M.Sc., M.Tech., Ph.D., PGDCA,

Assistant Professor in Physics

ABOUT THE CENTRE

      Crystal Growth Centre has been started functioning from 2004-2005 onwards in the Department of Physics, Aditanar College of Arts and Science, Tiruchendur.  The scholars in this centre concentrate on two main areas of  research namely   (i) Crystal Growth    and (ii) Nanoscience.  Some of the  facilities available in the Crystal Growth Centre are Furnace with temperature controller (Max. temperature reachable is 1200 oC), Two probe arrangement with temperature controller for measuring dielectric constant, loss and conductivity, LCR meter(Systronics make and Pacific make), Electronic balance,  pH meters, Hot plate magnetic stirrers, Microwave oven, Hot plates and ovens, Abbe’s refractometer, Digital multimeter for  measuring resistance (200 M W), He-Ne laser, Hydraulic press, Internet facility, Constant temperature bath and the like.
