Abstract
In a published paper, Acta Mater. 61 (2013) 294–309, Kamimura et al. estimated the Peierls stress of various ceramics and semiconductors based on experimental data by using a dislocation kink-pair theory. This paper shows that their calculated values of Peierls stress are incorrect, being one order of magnitude lower than the corrected values for most materials. Additionally, we assess the validity of the method for estimating the Peierls stress employed Kamimura et al.
期刊介绍：
Scripta Materialia is a LETTERS journal of Acta Materialia, providing a forum for the rapid publication of short communications on the relationship between the structure and the properties of inorganic materials. The emphasis is on originality rather than incremental research. Short reports on the development of materials with novel or substantially improved properties are also welcomed. Emphasis is on either the functional or mechanical behavior of metals, ceramics and semiconductors at all length scales.
