Self-driven ultraviolet photodetectors based on wide-bandgap semiconductors have been well investigated but are still being explored for further performance enhancement. Here we report a self-driven electrochemical ultraviolet photodetector (EUVPD) using a three-dimensional nanostructured photoanode based on defect-engineered TiO2 nanotube arrays (TNAs) modified with single-walled carbon nanotubes (SWCNTs) to enhance photoelectric performance.

Topographic essential synthesis of nanomaterials by adjusting easy preparatory factors is an effective way to improve a variety of nanostructured materials. The SILAR technique is used to evaluate the manufacturing samples of MoO3, TiO2, and MoTiO5 nanostructures. These nanostructures of MoO3, TiO2, and MoTiO5 are used as electrode materials in photovoltaic systems. The link between photoelectrochemical characteristics and MoO3, TiO2, and MoTiO5 nanostructures is studied in depth.

The pump-probe technique is a powerful tool for probing and characterizing the electronic and structural properties of short-lived excited states of materials. Upon the absorption of photons of the pump, excited states of the materials are established. Relaxation of these states reflects many physical aspects of the materials which can be tracked by a consequent beam – the probe.

Semiconductor nanostructures are currently one of the largest and most exciting areas in solid state physics. Low-dimensional electron systems (realized in semiconductor quantum structures) are particularly appealing because they allow one to study many-particle effects in reduced dimensions. Inelastic light scattering gives direct access to the elementary excitations of those systems.

Cathodoluminescence (CL) is a non-destructive technique to characterize optical and electronic properties of nanostructures in many kinds of materials. Major subject is to investigate basic parameters in semiconductors, impurities in oxides and phase determination of minerals. CL is similar to photoluminescence (PL) technique, but the excitation by high energy electrons can produce all the transition to the higher energy excitation states and induce light emission in the wide energy range concerned with versatile types of electronic transitions in materials....

The field of magnetic nanostructures is now an exciting and central area of modern condensed matter science, which has recently led to the development of a major new direction in electronics – so called ‘spintronics’. This is a new approach in which the electron spin momentum plays an equal role to the electrical charge, and these radical ideas have galvanised the efforts of previously disparate research communities by offering the promise of surpassing the limits of conventional semiconductors. Clearly the world of magnetism has now entered electronics in a very fundamental manner.
