Topological Insulators, Dirac and Weyl Semimetals

Topological insulators are a phase of matter in which the bulk material is semiconducting, but the surface has electrons that are chiral, massless, and conduct electricity and create metallic states.
Dirac semimetals are compounds with exotic electrons may exist inside the bulk solid.
Weyl semimetals are materials where valence and conduction bands cross in single points that called Weyl nodes.
Topological Insulators, Dirac and Weyl Semimetals, have opened up exciting possibilities in the field of condensed matter physics and materials science, and their study continues to be an active area of research.


Flexible (magneto)electronics, also known as flexible magnetics or flexible electronics with magnetic components, are an emerging field of technology that combines flexible or bendable substrates with magnetic materials for various applications. These materials and devices have the potential to revolutionize a wide range of applications, from wearable devices to sensorics and electronics.

Magneto dielectrics

Magnetic dielectrics materials that exhibit both magnetic and dielectric properties. They are typically insulating materials with intrinsic magnetic moments. These materials are interesting for various applications in electronics, telecommunications, and energy storage.
