Kinking in Semiconductor Nanowires: A Review
2021
The growth direction of nanowires (NWs) can change during synthesis as a result of stochastic processes or modulation of certain growth conditions. This phenomenon is known as kinking. Although deviations from a uniform vertical growth are typically considered to be undesirable, kinking opens a route for additional tweaking of the characteristics and functionalities of NWs in a controllable manner, thus extending the range of potential applications. In the present Review, we give an insight into the kinking mechanisms and summarize the most crucial factors that can lead to kinking of NWs during synthesis. Additionally, the properties and applications of kinked NWs are discussed. © 2021 The …

2014
Izdevums veltīts LU rektora M. Prīmaņa devumam LU attīstībā un ķīmijas zinātnē. Mārtiņš Prīmanis ieņēma LU rektora amatu no 1937. līdz 1940. gadam un no 1941. līdz 1944. gadam. Grāmatā iekļauts M. Prīmaņa dzīves un darba apraksts, dokumenti, fotogrāfijas, vairāki M. Prīmaņa publicētie darbi un viņa darbu bibliogrāfiskais rādītājs. Latvijas Ķīmijas vēstures muzeja darbinieku Dr. sc. ing. Ilgara Grosvalda un Dr. chem. Ulda Alkšņa rakstā analizēta profesora M. Prīmaņa zinātniskā, sabiedriskā un valstiskā darbība, kā arī izvērtēts darbs LU Ķīmijas fakultātes Neorganiskās ķīmijas tehnoloģijas katedras vadītāja, LU Ķīmijas fakultātes dekāna un LU rektora amatā. Izdevumā publicētie fragmenti no M.…
