Title | PHON - A program to calculate phonons using the small displacement method |
Description | I am not entirely sure if this is relevant, but here it is. The PHON code is a computer software that is used to compute vibrational frequencies of materials, and with them also compute their thermodynamic properties. The programme is freely available from my personal web-page, and also from Github and from the Computer Physics Communications website. |
Type Of Material | Improvements to research infrastructure |
Year Produced | 2009 |
Provided To Others? | Yes |
Impact | PHON is used by hundreds of groups worldwide, and the describing paper (Computer Physics Communication 180, 2622-2633 (2009)) has been already cited more than 400 times. I am associating this product with all my grants as I have been developing this code over the years, and so all my grants have contributed to sustain this development. |
