A variable probe pitch micro-Hall effect method

Hall effect metrology is important for a detailed characterization of the electronic properties of new materials for nanoscale electronics. The micro-Hall effect (MHE) method, based on micro four-point probes, enables a fast characterization of ultrathin films with minimal sample preparation. Here, we study in detail how the analysis of raw measurement data affects the accuracy of extracted key sample parameters, i.e., how the standard deviation on sheet resistance, carrier mobility and Hall sheet carrier density is affected by the data analysis used. We compare two methods, based primarily on either the sheet resistance signals or the Hall resistance signals, by theoretically analysing the effects of electrode position errors and electrical noise on the standard deviations. We verify the findings with a set of experimental data measured on an ultrashallow junction silicon sample. We find that in presence of significant electrical noise, lower standard deviation is always obtained when the geometrical analysis is based on the sheet resistance signals. The situation is more complicated when electrode position errors are dominant; in that case, the better method depends on the experimental conditions, i.e., the distance between the insulating boundary and the electrodes. Improvement to the accuracy of Hall Effect measurement results is crucial for nanoscale metrology, since surface scattering often leads to low carrier mobility

Eleganca resnosti branja mladinske književnosti

Prispevek se osredotoča na metodo interpretacije mladinske književnosti, ki jo izražajo strokovna besedila Helge Glušič. Izhaja iz temeljnih avtopoetik, ki poudarjajo kakovost in naslovniško univerzalnost te književne zvrsti. Obe izhodišči za razlago in vrednotenje je mogoče videti tudi pri avtoričinih interpretacijah mladinske književnosti, predvsem v knjigi Sto slovenskih pripovednikov. V njej se prepletata dva modela branja mladinske književnosti: interpretacija mladinskih besedil kot pomembnega dela celovitega avtorjevega opusa ter osredotočenost na mladinska besedila, če je avtor v literarni zgodovini označen kot ustvarjalec za mladino.The contribution is focused on the method of interpretation of youth literature as demonstrated by the expert texts of Helga Glušič. The point of departure is the fundamental autopoetics emphasising the quality and the reader universality of this literary genre. Both starting points for interpretation and assessment can be identified in the author\u27s interpretations of youth literature, particularly in A Hundred Slovenian Narrative Writers, in which two models of reading youth literature are intertwined: the interpretation of young readers\u27 texts as an important part of an author\u27s opus, and the focus on these texts in the case that an author has been marked in literary history as a youth writer
