residual_strain¶
- Calling sequence
strain{ residual_strain }
- Properties
using: \(\mathrm{\textcolor{Dandelion}{conditional}}\)
type: \(\mathrm{real\;number}\)
values:
[-1.0, 1.0]
unit: \(\mathrm{-}\)
- Dependencies
This group is not allowed if any of no_strain{ } and import_strain{ } is defined.
- Functionality
Residuals strain in the substrate \(\eta\) scales lattice parameter of the substrate (only for the purpose of strain computation) according to the formula \(a_{\eta,s}=(1+\eta)\cdot a_{0,s}\), where \(a_{0,s}\) is the (unstrained) lattice parameter of the substrate and \(a_{\eta,s}\) the modified (strained) lattice parameter of the substrate. The latter one represents the substrate during evaluation of the strain tensor.
- Example
strain{ residual_strain = 0.2 pseudomorphic_strain{} }
