 Solid State Physics

The research in this branch is carried out in the following fields:

  1. Magnetism, Superconductivity & Colossal Magnetoresistance
  2. Prof. Dr. Md. Feroz Alam Khan, Prof. Dr. A. K. M. Akther Hossain, M A Basith, Muhammad Samir Ullah, Mohammad Abu Sayem Karal, Mohammad Khurshed Alam and Md. Azizar Rahman are working in this group. Magnetic properties like magnetization, magnetic anisotropy and magnetostriction of hard and soft magnetic materials in the form of bulk, thin films and ribbons, are investigated.

    This group also investigates cuprate high Tc superconductors, and colossal magnetoresistance (CMR) in manganite perovskites. The CMR studies are performed in polycrystalline bulk and thick film samples. Couple of research projects are in progress in this field under the financial support of Bangladesh University of Engineering & Technology and the Ministry of Science & Technology, Government of the People’s Republic of Bangladesh. This group has collaboration with IPPS, Sweden and the department of Physics, University of Hanoi, Vietnam.

  3. Polymer Physics
  4. Prof. Md. Abu Hashan Bhuiyan, Dr. Md. Forhad Mina and Mohammad Jellur Rahman are now working with soft condensed matters, especially with polymeric materials. Prof. Bhuiyan has been working in this area since 1985. Currently this group is preparing polymer thin films by plasma polymerization technique and characterized them by various methods. Besides, this group is processing and developing noble polymer materials such as polymer blends and composites by extrusion molding, injection molding, hot pressing, etc. methods. The structural, electrical, mechanical, micromechanical, thermal, surface morphological etc. properties of these materials are characterized by various techniques and are correlated. These research programmes are undertaken considering the potential applications of the newly emerging properties of the Polymer Blends and Composites. This group has also further intension to develop methods for polymer crystallization. In addition, this group is also synthesizing ceramic materials and characterizing them. Mohammad Jellur Rahman is actively involved in this work.

  5. Crystal Growth and Thin Film
  6. Prof. Jiban Podder, Dr. Md. Mostak Hossain and Muhammad Samir Ullah work in this area. This group is engaged in studying the growth kinetics and habit modification of some technologically important non linear optical crystals from low temperature solutions growth technique. Structural, optical, electrical and mechanical properties of these grown crystals are studied. Prof. Jiban Podder also works on carbonization and graphitization of coal and organic compounds.

    Prof. Jiban Podder and Muhammad Rakibul Islam are now working with thin film. This group is preparing semiconductor thin films by spray pyrolisis deposition (SPD) technique with an aim of finding suitable applications in solar cell and The structural, optical, electrical, mechanical, thermal, and surface morphological, etc. Properties of as deposited films are characterized by various techniques.

  7. Nanotechnology
  8. Nanotechnology, in general, refers to the arena of research dealing with matter at dimensions of roughly 1 to 100 nanometers, where unique phenomena enable novel applications. Encompassing nanoscale science, engineering and technology, nanotechnology involves synthesis, modeling, characterization, and manipulating properties of matter at this nanoscale. Although the exploration of novel nano-materials for various applications sounds exciting, state-of-the art research demands a dedicated nanotech research laboratory with modern experimental and analytical facilities. Keeping this in mind and also to keep pace with modern trend in research in related fields, Dr. Mohammed Abdul Basith is gradually building up a Nanotechnology Research Laboratory (NRL) at the Dept. of Physics, BUET. Since its inception in April 2014, different infrastructural facilities have been provided by BUET authority. The task of developing various synthesis and characterization facilities in such a short time-span is quite daunting, however, this has been established through research grants for our various projects from home and abroad. Currently, Dr. Basith is working on various research projects such as (i) Solar hydrogen production via water splitting using locally dveloped novel photcatalysts. (ii)Structural, dielectric, ferroelectric and magnetic properties and Tunable exchange bias effect in rare earth doped multiferroics. (iii) Development of top-down preparation technique of multiferroic nanoparticles directly from bulk material. (iv)Synthesis and characterization of multiferroic and magnetites nanoparticles. (v) Micromagnetic simulations of the influence of edge profiles of ferromagnetic nanowires on the magnetic behavior of domain walls. (vi) Understanding and controlling of domain wall behavior in ferromagnetic nanowires by ion irradiated pinning features using micromagnetic simulations.


     

    Health Physics, Medical Physics & Radiation Protection

    Dr.Afia Begum works in this branch. This group has an active collaboration with Radio Physics Department of Gummersbach Hospital, University of Cologne, Essens University, Essens and German Cancer Research Center (DKFZ), German and Atomic Energy Commission, Bangladesh. Research works in this branch include mainly cross-section measurement for neutron induced reaction on cancer treatment planing, radiation dosimetry and environmental radioactivity and radiation protection using high energy photon beam. This group also investigates the quality control of the machines used in diagnosis and treatment of cancer with radiation.


     

    Atmospheric Physics

    Dr. Md. Rafi Uddin and Dr. Nasrin Akter are working in this area. Research is concentrated mainly in the field of Satellite Meteorology, Radar Meteorology, Monsoon Meteorology and Tropical Cyclone. He is currently involved in "Japan-Bangladesh Joint Study Project" Phase II, Topic-I, Meteorology Section for investigating rainfall characteristics and diurnal variation of rainfall in Indian Subcontinent. The project is funded by Japan International Co-operation Agency (JICA). He is also involved in a "Monbusho" project with Disaster Prevention Research Institute (DPRI), Kyoto University; funded by Grant Aid of Ministry of Education, Culture and Sport in Japanese Government, Japan, for investigating cause of natural disaster like flood in this region.
