INSTITUTE OF PHYSICS (update: 14.03.2017)
Within the Intitute of Physics, the advanced scientfic research is conducted on the fields of: nanotechnology, molacular bioelectronics, superficial semi-conductor and metallic structures as well as computer simulations. The scientfic research are conducted in three scientific units:
Z1 - Division of Molecular Physics
is a scientific unit conducting research into the applications in photodynamic therapy and tumor diagnosis as well as molecular bioelectronics. The scientific activity of the unit
is focused on the research into the processes of conversion of the light energy into electrical energy in the photoelectrochemical cell with organic dyes,
synthetic and natural elements of the photosynthesis apparatus. The relationships between structure and function of the photosynthesis apparatus are investigated into,
as well as mechanism of the deactivation of the energy of the excited molecules and macromolecules and sets of them, and especially the interation between dye – dye
and dye – surroundings. Recently, object of interest is also the excitation of surface plasmons of the molecular dyes in the Langmuir-Blodgett layers and on the
quantum points. The research is also conducted into the mechanical properties of the molecular sets using the atomic forces’ spectroscopy (ATM).
Second important field of interest are spectral properties of the photosensitive dyes and their application in the photodynamic therapy
and in the diagnosis of tumors.
Z2 – Division of Surface Physics and Nanotechnology (update: 12.01.2016)
is a scientific unit conducting research upon the structural and electron properties of nanostructures and solid state surfaces in the nanometer scale. In the division’s field of interest there are objects in nanoscale, in which the properties of the matter are subject to the yet-not-investigated-into combination of quantum and classical physics laws. Particularly, the basic relationships between the structure and physical properties in nanoscale are studied. At present, our research is focused on investigations of metal silicides and germanides nanostructures, low dimensional structures of organic molecules, graphene and graphene-like materials from the point of view of their application in electronics of high integrity. The division is also conducting works on developing of semiconductor sensors, especially magnetic field sensors based on the Hall phenomenon and Extraordinary Magnetoresistance Effect (EMR) using also graphene as working layer.
Z3 – Division of Computational Physics and Nanomechanics (update: 23.03.2017)
conducts research in materials modeling and simulations at various scales from atomic to micro to macroscale. Among the topics are: simulations of the mechanical properties of nanometer scale materials and individual molecules; simulations of friction and adhesion phenomena by molecular dynamics methods; studies of the surface electronic structure of traditional and topological semiconductor materials using DFT methods; simulations of the mechanical properties of metamaterials, in particular materials with negative Poisson’s ratio and negative mechanical susceptibility. In addition to computer simulations, experimental research on the phenomena of adhesion and friction at the nanometer scale and the mechanical properties of individual molecules are also performed.
INSTITUTE OF MATERIALS RESEARCH AND QUANTUM ENGINEERING
The research activity carried out by the members of the Institute of Material Research and Quantum Engineering (IMRQE) are focused on characterization of micro- and nanostructured organic and inorganic functional materials with high technological potential for application in optoelectronics, photonics and medical treatment. A part of the scientist is focused on development of advanced methodologies for atomic spectroscopy and quantum engineering. The institute consists of three parts:
Z1 - Division of Micro- and Nanostructures(update: 28.01.2016)
is a research unit engaged in the study of thermodynamic, UV-Vis spectral, and electrical properties of ultrathin molecular layers (Langmuir monolayers and Langmuir-Blodgett films), and also thin organic layers (zone-casted and spin-coated) formed from dyes, liquid crystals, liquid crystal polymers, and mixtures thereof. The lab also conducts the research of molecular orientational order in anisotropic liquid crystal layers (nematics and smectics A) doped with fluorescent dyes. The structures produced in the lab are important for molecular electronics and especially for optoelectronics. The organic layers are characterized by the absorption spectroscopy and fluorescence methods in the UV Vis range and also the polarized optical microscopy (POM, BAM) and atomic force microscopy (AFM) methods. The aim of the study is to reveal the nature of intermolecular interactions (molecular aggregation) and to determine molecular orientational order parameters, as well as to reveal the morphology of the layers and to examine the electrical conductivity of the layers.
Z2 - Division of Optical Spectroscopy (update: 08.03.2016)
DOS conducts studies of physical properties and processes in organic and inorganic functional materials and bio-materials with the use of Raman and Brillouin, ultrasonic spectroscopy methods and the Maker Fringes method (nonlinear optical technique). The main efforts of DOS’s research are focused on the following materials:
Z3 – Division of Engineering and Quantum Metrology (update: 08.01.2016)
Based on the laser atom spectroscopy the research of the Laboratory is currently devoted to the physical phenomena used in quantum engineering and metrology. Within the unit operate unique laboratories on the fields of: spectroscopy ‘laser-microwaves’ in the electromagnetic Paul’s trap, spectroscopy ‘laser-microwaves’ on the atom stream, spectroscopy with the fluorescence induced by laser radiation. The mentioned laboratories have been created according to the Laboratory’s own projects and, as far as its technological level is concerned, they are comparable with the leading laboratories in Europe. In the mentioned laboratories students discover the secrets of the experiments, which enable to manipulate the free atoms and ions in the conditions of the ultra-high vacuum. Familiarising with the technic of double optic-microwave resonance and with the method of counting single quants emitted by the atom or ion enables to conduct the measurements with accuracy of 10-9, that is with the accuracy of the several parts-per-billion of the measured object. Technology and rules of conducting experiment based on the atoms’ stream are similar to those applied in the atom clock (Cesium clock). Yet the experiences with the usage of electromagnetic traps enable to fathom the phenomena used for creating elements of quantum computer. Students have the possibility of getting to know how an equipment with such capacities is projected, constructed and - later on -exploited. They also get to know various laser techniques, applied in the scientific research, as well as in different sorts of technologies.
