Abstract:
Semiconducting materials are important photonic materials and the technologies developed have been utilized in many fields of the modern society and they are closely related to the quality of our life. The main applications of the materials are for light source and sensing originated from interaction of photons and matters. In this invited talk, I will first present our work on the properties of the semiconducting materials and their applications as lasers and photodetectors, and then present integrated hybrid subwavelength structures which show significant enhancement on device performance.

Abstract:
Ab initio Quantum-Mechanical methods are well-established tools for material characterization and discovery in many technological areas. Recently, state-of-the-art approaches based on density-functional theory and many-body perturbation theory were successfully applied to semiconducting alkali antimonides and tellurides, which are currently employed as photocathodes in particle accelerator facilities. The results of these studies have unveiled the potential of ab initio methods to complement experimental and technical efforts for the development of new, more efficient materials for vacuum elec

Abstract:
This paper reviews synthetic concepts for the functionalization of various inorganic nanoparticles with a shell consisting of organic polymers and possible applications of the resulting hybrid materials. A polymer coating can make inorganic nanoparticles soluble in many solvents as individual particles and not only do low molar mass solvents become suitable, but also polymers as a solid matrix. In the case of shape anisotropic particles (e.g., rods) a spontaneous self-organization (parallel orientation) of the nanoparticles can be achieved, because of the formation of lyotropic liquid crystall

Abstract:
We present an ab initio computational approach for the calculation of resonant Raman intensities, including both excitonic and nonadiabatic effects. Our diagrammatic approach, which we apply to two prototype, semiconducting layered materials, allows a detailed analysis of the impact of phonon-mediated exciton-exciton scattering on the intensities. In the case of bulk hexagonal boron nitride, this scattering leads to strong quantum interference between different excitonic resonances, strongly redistributing oscillator strength with respect to optical absorption spectra. In the case of MoS2, we

Abstract:
Quantum computing is based on physical materials. The choice of material is important, and semiconductor materials have become a widely trailed choice in recent years. A lot of initial research into quantum computing only manifested that it could operate at temperatures close to absolute zero. However, because semiconductors are now used in the construct of these systems, it has enabled researchers to utilize quantum computers in room temperature conditions. This is one of the major reasons why quantum computing is close to commercial realization, so the role played by semiconductors is of major importance. It is true that the implementation of semiconductors has been challenging in its own way. Many semiconducting materials can exhibit many quantum degrees of freedom, and this causes the qubits to interact with each and decode quickly. Here the authors try to project a systematic study of different semiconducting materials used for quantum computing.

Abstract:
Quantum dots (QDs) are very small nanoparticles and are composed of hundreds to thousands of atoms. These semiconducting materials can be made from an element, such as silicon or germanium, or compounds such as cadmium sulphide (CdS) or cadmium selenide (CdSe). The colour of these small particles does not depend on the type of semiconducting material from which the dots are made, but rather on its diameter. Besides, ODs attract the most attention because of their unique visual properties. Therefore, these are used in all kinds of applications where precise control of coloured light is important. As these dots are of great importance in chemical, biological and medical applications, they can be designed to deliver anti-cancer drugs and direct them to specific areas of the body. Therefore, with this technique, the harmful side effects of chemical treatments can be reduced. It is possible to examine and study the properties of these nanomaterials and make sure they are analyzed using some scientific devices and techniques, the most important of which are: transmittance electron microscopy (TEM), scanning electron microscopy (SEM), atomic forces microscopy (AFM) with dielectrics, and X-ray diffraction (XRD). This chapter opens horizons towards knowing what quantum dots are and their unique properties, as well as methods of preparation and then placing our hands on the chemical, and biological applications of these dots.
