Resumen
In this article, two concepts of temperature, i.e., Burns temperature for relaxor ferroelectrics and quantum temperature scale for quantum paraelectrics, are reviewed briefly. Since both temperatures describe the deviation of the dielectric constant from Curie–Weiss law, their relationship is discussed. Finally the concept of quantum temperature scale is extended to demonstrate the evolution process of quantum paraelectric behavior to relaxor ferroelectric behavior.

Resumen
The dielectric and magnetic polarizations of quantum paraelectrics and paramagnetic materials have in many cases been found to initially increase with increasing thermal disorder and hence, exhibit peaks as a function of temperature. A quantitative description of these examples of “order-by-disorder” phenomena has remained elusive in nearly ferromagnetic metals and in dielectrics on the border of displacive ferroelectric transitions. Here, we present an experimental study of the evolution of the dielectric susceptibility peak as a function of pressure in the nearly ferroelectric material, stro

Resumen
Le déploiement de la technologie 5G a soulevé des préoccupations significatives concernant la consommation d'énergie. Celle-ci peut être minimisée en ajustant l'impédance de l'antenne à 50 ohms. Pour répondre aux exigences de la 5G et du NFC, un circuit d'adaptation d'impédance contrôlable en tension avec une capacité hautement modulable (varactor) est nécessaire. Plus précisément, un rapport de réglage d'au moins 5 et de faibles pertes diélectriques dans la bande 5G (2-5 GHz) sont essentiels pour préserver l'efficacité énergétique (courant de fuite ~1 nA).

Resumen
The thesis is organized as follows. In the rest of this introductory chapter we review in more detail the main relevant experiments, and point to some implications of these for our model building. Chapter 2 is devoted to a general discussion of models to be treated in subsequent chapters. First we recall the well-known displacive versus orderdisorder regime aspects of the standard classical model for structural phase transitions, and discuss the extent to which these aspects pertain to the case of QPE perovskites. Correspondingly, we divide the possible models into two classes, those bas

Resumen
Un SrTiO3 paraélectrique quantique est un matériau situé à proximité d'un point critique quantique de la transition ferroélectrique dans lequel la température critique vers l'état ferroélectrique est supprimée jusqu'à 0 K. Cependant, la compréhension du comportement de la transition de phase à proximité de ce point reste problématique. Ici, nous étudions les solutions solides basées sur le SrTiO3 pour approcher les régions pré-critiques du diagramme de phase et étudions le résultat de la coexistence des fluctuations quantiques et du mouvement thermique.

Resumen
Ferroelectric materials have been extensively studied theoretically and experimentally for many decades. Their ferroelectric, piezoelectric, pyroelectric, dielectric and electro-optical properties offer great promise in various applications such as non-volatile random access memory devices, non linear optics, motion and thermal sensors, and tunable microwave devices. Advanced applications for high dielectric constant insulators and nonvolatile memories in semiconductor industry have led to a meteoric rise of interest in the ferroelectrics recently.

Resumen
Among the lead-free perovskite-structure materials, strontium titanate (SrTiO3—ST) and potassium tantalate (KTaO3—KT), pure or modified, are of particular importance. They are both quantum paraelectrics with high dielectric permittivity and low losses that can find application in tunable microwave devices due to a dependence of the permittivity on the electric field. Factors as Sr/Ti and K/Ta ratio in ST and KT ceramics, respectively, can alter the defect chemistry of these materials and affect the microstructure. Therefore, if properly understood, cation stoichiometry variation may be intenti

We have developed highly efficient microcavity wavelength conversion devices that are adaptable to crystals lacking birefringence or ferroelectricity. In this study, we employed a low birefringence paraelectric SrB4O7 crystal, which exhibits significant potential for wavelength conversion and high transparency down to 130 nm. Using this crystal, we successfully achieved 199 nm vacuum-ultraviolet second harmonic generation with a picosecond laser. The achieved wavelength of 199 nm is shorter than the theoretical minimum of 205 nm for second harmonic generation in BaB2O4. Our device holds promis
