Total-dose radiation response of hafnium-silicate capacitors

Microstructure and optical properties of Pr3+-doped hafnium silicate films

In this study, we report on the evolution of the microstructure and photoluminescence properties of Pr3+-doped hafnium silicate thin films as a function of annealing temperature (TA). The composition and microstructure of the films were characterized by means of Rutherford backscattering spectrometry, spectroscopic ellipsometry, Fourier transform infrared absorption, and X-ray diffraction, whil...

Importance of total radiation dose and overall treatment time in T1 early glottic cancer

Background: In this study, we retrospectively reviewed the treatment outcome of 63 patients with T1 early glottic cancer treated with RT alone to determine the treatment outcome and the prognostic factors affecting local control. Materials and Methods: All patients were treated by 6 MV photons with conventional bilateral fields up to a median dose of 66 Gy in 33 fractions. Results: The 5-year l...

Determination of Dose-Equivalent Response of A Typical Diamond Microdosimeter in Space Radiation Fields

Introduction: Microdosimeters are helpful for dose equivalent measurement in unknown radiation fields. The favorable physical and mechanical properties of the detector-grade chemical vapor deposition diamond materials have made the diamond microdosimeters suitable candidate for radioprotection applications in space. The purpose of this work is the investigation of the dose equivalent response o...

The Radiation Response of the High Dielectric-Constant Hafnium Oxide/Silicon System

We have explored the radiation response of the HfO2/Si system with a combination of capacitance versus voltage and electron spin resonance measurements on capacitor and bare oxide structures subjected to Co gamma irradiation and vacuum ultraviolet irradiation. Our studies have utilized both (100)Si and (111)Si substrate structures. Capacitors have been irradiated under both positive and negativ...
