  • Low-frequency noise measurements used for quality assessment of GaSb based laser diodes prepared by molecular beam epitaxy 

    Chobola, Zdeněk; Luňák, Miroslav; Vaněk, Jiří; Hulicius, Eduard; Kusák, Ivo (Faculty of Electrical Engineering and Information Technology of the Slovak University of Technology, 2015-08-01)
    The paper reports on a non-destructive method of reliability prediction for semiconductor lasers diodes GaSb based VCSE. Transport and noise characteristic of forward biased were measured in order to evaluate the new MBE ...
  • Methods for recycling photovoltaic modules and their impact on environment and raw material extraction 

    Strachala, Dávid; Hylský, Josef; Vaněk, Jiří; Fafilek, Günter; Jandová, Kristýna (Acta Montanistica Slovaca, 2017-12-11)
    This work deals with methods of recycling of photovoltaic modules and evaluates contribution of recycling to the environment and reduction of raw materials extraction. The article describes the materials needed to manufacture ...
  • Redox and optically active carbohelicene layers prepared by potentiodynamic polymerization 

    Hrbáč, Jan; Pavelka, Vit; Crassous, Jeanne; Žádný, Jaroslav; Fekete, Ladislav; Pokorný, Jan; Vanýsek, Petr; Storch, Jan; Vacek, Jan (Elsevier, 2020-02-19)
    This short paper describes the preparation of thin layers based on carbohelicenes, which are inherently chiral polyaromatics existing in the enantiomeric forms P and M. Specifically, [5]-, [6]- and [7]helicene were subjected ...
  • Sodno-iontové akumulátory - budoucnost a aktuální vývoj 

    Libich, Jiří; Sedlaříková, Marie; Vondrák, Jiří; Máca, Josef; Čech, Ondřej; Fíbek, Michal; Čudek, Pavel; Chekannikov, Andrey; Fafilek, Günter (NZEE, 2019-05-15)
    The lithium-ion technology is widely known and spread technology. The based of this technology lies on transport of lithium ions during charging or discharging from one electrode to the other, this principle is call “rocking ...
  • Supercapacitors: Properties and applications 

    Libich, Jiří; Máca, Josef; Vondrák, Jiří; Čech, Ondřej; Sedlaříková, Marie (Elsevier, 2018-03-26)
    Energy accumulation and storage is one of the most important topics in our times. This paper presents the topic of supercapacitors (SC) as energy storage devices. Supercapacitors represent the alternative to common ...
