  • BOLUN, Ion (Tehnica UTM, 2019)
    In examined homogeneous multi-optional systems, the decision is made on two or more final options, consisting of parts of a homogeneous resource measured in integers; the resource in question is apportioned to beneficiar ...
  • VERJBITKI, Valeriu; RAILEAN, Serghei; LUPAN, Oleg (Tehnica UTM, 2019)
    The development of new technologies for extracting and testing the parameters of nanostructures based on semiconductor oxides required the development of special instruments for measuring the parameters of such structures ...
  • BRAGARENCO, Andrei; MARUSIC, Galina (Tehnica UTM, 2019)
    The paper discusses the importance of contemporary electronic systems, with the focus on the development of distributed electronic equipment. Here the devices, potentially members of an Internet of Things (IoT) network, ...
  • KONOPKO, Leonid; NIKOLAEVA, Albina; HUBER, Tito; ROGACKI, Krzysztof (Tehnica UTM, 2019)
    Bulk bismuth has been classified as a trivial topological insulator (TI) where the surface states do not have topological protection. Still, the electronic mobility of surface states is exceptionally large. This is not ...
  • KONOPKO, Leonid; NIKOLAEVA, Albina; HUBER, Tito; ROGACKI, Krzysztof (Tehnica UTM, 2019)
    Recently a new class of insulator, namely, topological insulator (TI) [1], was proposed. A TI is a material with a bulk electronic excitation gap generated by the spin-orbit interaction, which is topologically distinct ...
