[{"abstract":[{"lang":"eng","text":"Specific heat capacity measurements by differential scanning calorimetry (DSC) of single crystals of solid solutions of LiNbO3 and LiTaO3 are reported and compared with corresponding ab initio calculations, with the aim to investigate the variation of the ferroelectric Curie temperature as a function of composition. For this purpose, single crystals of these solid solutions were grown with Czochralski pulling along the c-axis. Elemental composition of Nb and Ta was investigated using XRF analysis, and small samples with homogeneous and well known composition were used for the DSC measurements. We observed that the ferroelectric Curie temperature decreases linearly with increasing Ta concentration in the LiNb1−x Tax O3 solid solution crystals. Furthermore, the ferroelectric transition width of a mixed crystal appears to be smaller, as compared to pure LiTaO3."}],"publication":"Ferroelectrics","keyword":["Condensed Matter Physics","Electronic","Optical and Magnetic Materials"],"language":[{"iso":"eng"}],"year":"2023","quality_controlled":"1","issue":"1","title":"Solid solutions of lithium niobate and lithium tantalate: crystal growth and the ferroelectric transition","publisher":"Informa UK Limited","date_created":"2023-10-11T09:10:08Z","status":"public","type":"journal_article","article_type":"original","extern":"1","_id":"47996","user_id":"22501","citation":{"apa":"Bashir, U., Böttcher, K., Klimm, D., Ganschow, S., Bernhardt, F., Sanna, S., Rüsing, M., Eng, L.

Structural parameters such as the crystal volume and the lattice parameters a and c vary roughly linearly from LiTaO3 to LiNbO3, showing only minor deviations from the Vegard behavior. Our ab initio calculations demonstrate that the TO1, TO2 and TO4 vibrational modes become harder with increasing Nb concentration. TO3 becomes softer with increasing Nb content, instead. Furthermore, the investigated zone center A1 -TO phonon modes are characterized by a pronounced stoichiometry dependence. Frequency shifts as large as 30 cm−1 are expected as the [Nb]/[Ta] ratio grows from 0 to 1. Therefore, spectroscopic techniques sensitive to the A1 modes (such as Raman spectroscopy), can be employed for a direct and non-destructive determination of the crystal composition."}],"status":"public","type":"journal_article","publication":"Ferroelectrics","keyword":["Ferroelectrics","vibrational properties","LiNbO3","LiTaO3","mixed crystals"],"language":[{"iso":"eng"}],"project":[{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"_id":"13520","user_id":"14931","department":[{"_id":"15"},{"_id":"170"},{"_id":"295"},{"_id":"230"}]},{"language":[{"iso":"eng"}],"department":[{"_id":"15"},{"_id":"170"},{"_id":"295"},{"_id":"35"},{"_id":"230"},{"_id":"27"}],"user_id":"16199","_id":"13519","project":[{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"}],"status":"public","publication":"Ferroelectrics","type":"journal_article","doi":"10.1080/00150193.2013.821904","title":"LiNb1-xTaxO3Electronic Structure and Optical Response fromFirst-PrinciplesCalculations","volume":447,"date_created":"2019-09-30T13:49:40Z","author":[{"last_name":"Riefer","full_name":"Riefer, A.","first_name":"A."},{"first_name":"S.","full_name":"Sanna, S.","last_name":"Sanna"},{"last_name":"Schmidt","orcid":"0000-0002-2717-5076","id":"468","full_name":"Schmidt, Wolf Gero","first_name":"Wolf Gero"}],"date_updated":"2025-12-05T10:30:58Z","page":"78-85","intvolume":"       447","citation":{"apa":"Riefer, A., Sanna, S., &#38; Schmidt, W.

Firstly, the phonon modes of bulk and of the (0001) surface are calculated by means of the density functional theory. Our calculations reveal the existence of localised vibrational modes both at the positive and at the negative surface. The surface vibrations are found at energies above and within the bulk bands. Phonon modes localised at the positive and at the negative surface differ substantially. In a second step, the Raman spectra of LiNbO3 bulk and of the two surfaces have been measured. Raman spectroscopy is shown to be sensitive to differences between bulk and surface and between positive and negative surface. The calculated and measured frequencies are in agreement within the error of the method.","lang":"eng"}],"status":"public","type":"journal_article","publication":"Ferroelectrics","title":"Localised Phonon Modes at LiNbO3(0001) Surfaces","doi":"10.1080/00150193.2011.594396","publisher":"Informa UK Limited","date_updated":"2025-12-16T11:29:20Z","author":[{"full_name":"Sanna, S.","last_name":"Sanna","first_name":"S."},{"first_name":"Gerhard","full_name":"Berth, Gerhard","id":"53","last_name":"Berth"},{"first_name":"W.","full_name":"Hahn, W.","last_name":"Hahn"},{"first_name":"A.","last_name":"Widhalm","full_name":"Widhalm, A."},{"id":"606","full_name":"Zrenner, Artur","orcid":"0000-0002-5190-0944","last_name":"Zrenner","first_name":"Artur"},{"orcid":"0000-0002-2717-5076","last_name":"Schmidt","id":"468","full_name":"Schmidt, Wolf Gero","first_name":"Wolf Gero"}],"date_created":"2018-09-20T11:26:53Z","volume":419,"year":"2011","citation":{"apa":"Sanna, S., Berth, G., Hahn, W., Widhalm, A., Zrenner, A., &#38; Schmidt, W.
