Generation of terahertz oscillations by supercooled in electric field superconductors. Preliminary results

The electroplastic effect in materials is an interesting and potentially useful phenomenon in which an applied electric field affects the plastic flow properties of materials under strain. We have undertaken a study to use optical methods to monitor changes in alkali halide crystals undergoing the electroplastic effect. Some preliminary results from this work are presented along with more conventional quasi-static measurements of the electroplastic effect.

Terahertz Oscillations

Terahertz (THz) oscillations in n[Formula: see text]nn[Formula: see text] In[Formula: see text]Ga[Formula: see text]As diodes have been simulated with the use of a time-dependent hydrodynamic model. Under proper biased voltage and doping concentration, THz self-oscillations show up. The current self-oscillations originate from the formation and propagation of electric field domains in In[Formula: see text]Ga[Formula: see text]As diodes. The In[Formula: see text]Ga[Formula: see text]As device studied here may be presented as an excellent candidate as a solid-state THz source for monolithic integration.

Abstract The experimental outcomes of single bubbles nucleated and growth from a heated surface immersed in an electric field in high-quality microgravity level are presented. Data were obtained between September 2019 and January 2021 from the European experiment known as Reference mUltiscale Boiling Investigation (also multiscale boiling project), in which single bubbles of FC-72 were nucleated on a heated surface, on-board the International Space Station. In the experiments reported here, an electrostatic field is imposed in the boiling region by a washer-shaped electrode, centred above the nucleation site. The bubbles are heavily distorted by the electric stresses; in particular, contact angles and contact line length increase with electric field intensity. In the appropriate conditions, bubbles are continuously and regularly sucked towards the electrode, because they are attracted to regions of weaker electric field. The significant contribution of electro-convection is highlighted by the bubbles growth rate. These preliminary results contribute to the insight of the basics of boiling and show promising opportunities for practical application of electric fields in space.

Breakdown Electric Field

Dopants such as Ta2O5 play a major role in the formation of barriers at the grain boundary in TiO2 varistors, increasing their nonlinear coefficient and decreasing their breakdown electric field. This paper discusses the microstructural and physical properties of Ta- and Cr-doped TiO2 systems in which imported tantalum oxide was replaced with an equivalent Brazilian raw material. Preliminary results confirm that this national oxide can be utilized to obtain electroceramics such as varistors.
