2. Time-of-flight photoconductivity investigation of high charge carrier mobility in ▫$Ti_3C_2T_x$▫ MXenes thin-filmJurij Urbančič, Erika Tomsic, Manisha Chhikara, Nadiia Pastukhova, Vadym Tkachuk, Alex Dixon, Andraž Mavrič, Payam Hashemi, Davood Sabaghi, Ali Shaygan Nia, Gvido Bratina, Egon Pavlica, 2023, izvirni znanstveni članek Opis: Charge transport through a randomly oriented multilayered network of two-dimensional (2D) Ti3C2Tx (where Tx is the surface termination and corresponds to O, OH and F) was studied using time-of-flight photoconductivity (TOFP) method, which is highly sensitive to the distribution of charge carrier velocities. We prepared samples comprising Ti3C2Tx with thickness of 12 nm or 6-monolayers. MXene flakes of size up to 16 μm were randomly deposited on the surface by spin-coating from water solution. Using TOFP, we have measured electron mobility that reached values up to 279 cm2/Vs and increase with electric-field in a Poole-Frenkel manner. These values are approximately 50 times higher than previously reported field-effect mobility. Interestingly, our zero-electric-field extrapolate approaches electron mobility measured using terahertz absorption method, which represents intra-flake transport. Our data suggest that macroscopic charge transport is governed by two distinct mechanisms. The high mobility values are characteristic for the intra-flake charge transport via the manifold of delocalized states. On the other hand, the observed Poole-Frenkel dependence of charge carrier mobility on the electric field is typical for the disordered materials and suggest the existence of an important contribution of inter-flake hopping to the overall charge transport.

7. Raspredelenie predprinimatel'skih sposobnostej i migracija : struktura zanjatosti, neravenstvo dohodov i blagosostojanieD. A. Pokrovskij, Alexander Shapoval, 2015, izvirni znanstveni članek Opis: The authors define a general equilibrium model with heterogeneous
individuals who are endowed with identical preferences, given by the utility function with constant elasticity of substitution (CES), and with heterogeneous entrepreneurial skills. We find that scale effects linked to migration can be analyzed within the framework of the constructed model because the migration changes the market size together with a market structure. A population growth due to immigration of low-qualified individuals ambiguously affects the share of reciprocal to entrepreneurial
and the inequality in the economy. If the distribution of the inverse entrepreneurial skills has an increasing (decreasing, constant) elasticity, then decreases (increases, and does not change) and the Gini coefficient increases (decreases and does not change).
