Using nucleation kinetics of GaN as a sensitive probe we show that a thin ZrN layer strongly increases the substrate temperature, which significantly affects the dimensions and density of the nanowires. To quantify the effect we developed a technique of optical pyrometer calibration that allows reliable determination of emissivity, and thus precise measurement of temperature of substrates with unknown optical parameters, such as ZrN buffers of various thicknes","authors_text":"Aleksandra Wierzbicka, Karol Olszewski, Marek Guziewicz, Marta Sobanska, Zbigniew R.
