The scaling of the traditional silicon MOSFETs, which are the basic devices of modern electronics, had resulted already in the channel length of 5 nm order. However, its further miniaturization faces the obstacles of fundamental nature: electrons in the ultra-short channels are tunneling freely through the barrier, and the current in the source-drain circuit is no longer governed by the gate...
X-ray image detectors have been developed for medical and non-destructive testing applications. This study shows the improvement of the resolution of the scintillator, which is an indirect conversion type X-ray image detector. The emission of the scintillator is diffused and the spatial resolution of detector is reduced. Therefore, the scintillator was optically separated using silicon that...
CdTe semiconductor has been used as radiation detectors at room temperature. Impurity doping of CdTe has been considered difficult because it requires high temperature heat treatment and characteristics are degraded. However, the laser doping method that we have recently developed is overcoming this problem. When doping semiconductors, not all dopants act as donors or acceptors, and some of...
Imaging using X-rays is currently used in a wide range of fields such as medical, industry and security.The most common type of detector in use today is the indirect conversion method.In the indirect conversion method, X-rays are converted into visible light by a material called a scintillator. In the indirect conversion method, X-rays are converted into visible light by a substance called a...
This presentation focuses on functional nanomaterials with good surface plasmon resonance properties including Ag and conductive F/Sb doped SnO2 nanoparticles synthesized via facile chemical routes. Ag nanoparticles (NPs) with the size less than 10 nm were fabricated in TiO2-SiO2 photosensitve composite film showing prominent SPR absorption spectra at around 350-500 nm with its peak at 410 nm....
In this work, ZnO rod/film homojunction structure was fabricated on Sb-doped ZnO film. The Sb-doped ZnO films were prepared by sol-gel spin coating technique onto the ITO substrate then annealed in nitrogen, air and argon followed by low-temperature hydrothermal process to obtain ZnO rod structure. The morphology of Sb-doped ZnO film exhibit the ZnO nanoparticle with smaller and increasing...
Mn and Fe-incorporated BiVO4 nanoparticles with different doping contents were synthesized via one-step sonochemical method. XRD results show the essential structure of monoclinic BiVO4 structure and secondary phases were clearly found in form of metal-based oxide as MnO, Mn3O4, Mn2O3 and Fe2O3 compounds suggesting the incorporation of Mn and Fe ions. In addition, the effect of higher Fe...
