DESCRIPTION:Speakers: Anatoly Kiselev (Federal State government-financed r
 esearch institution  Institute of Solid State Chemistry of the Ural Branch
  of the Russian Academy of Sciences)\nThe technique for establishing the o
 ptical characteristics of metal-lic systems from synchrotron reflection sp
 ectra allows one to establish characteristics for the required range of lo
 w energy values. It is pro-posed to use the procedure for evaluating the e
 lectronic properties of aluminum by experimentally investigating the spect
 rum of optical conductivity with subsequent calculation of the Kramers-Kro
 nig inte-gral relations and the analytical between optical functions. For 
 com-parison\, the results of processing the spectrum of the optical conduc
 -tivity of an ellipsometric experiment are presented for a range of en-erg
 y values from 0.5 to 3 eV. A feature of the approach for determin-ing the 
 electronic characteristics of metal systems by minimizing the deviation of
  the model optical conductivity curve from the experi-mental one is the va
 riation in the effective mass of the electrons. When using ellipsometry da
 ta\, the determined electronic characteris-tics change quite sequentially 
 with a change in the effective mass val-ue. The use of data obtained from 
 synchrotron spectra shows the presence of significant local jumps in the m
 easured values at certain effective masses. Perhaps this is determined by 
 the imperfection in the numerical approaches of interpreting the data of t
 he synchrotron ex-periment. When modeling optical conductivity\, we can su
 mmarize the contributions from interband conductivity under the influence 
 of pho-ton energy. In the case of permittivity\, cross-contributions shoul
 d also be considered.   \nThe research was carried out within the state as
 signment of FASO of Russia (theme № АААА-А19-119031890028-0)\n\nhtt
