1. Growth of mercuric iodide crystals
Mercuric Iodide (HgI2) is a semiconductor candidate for the construction of X- and gamma-ray detectors for digital medical imaging due to its high atomic number (Z Hg = 80, Z I = 53). Also, HgI2 has a wide optical band-gap (2.13 eV) and high photon absorption coefficient for high-energy radiation. Different structures can lead to varying electrical and optic

2. Mercuric iodide (HgI2) for applications in radiation detectors / Iodeto de mercúrio (HgI2) para aplicações em detectores de radiação.
Recently, attention has been devoted to the study of mercuric iodide (HgI2) because this material is a strong candidate for the development of X- and γ -ray detectors. This material has an optical gap of 2.13 eV, high atomic number (ZHg = 80; ZI = 53) and high absorption coefficient for radiation in the wavelength region of X- and γ rays. When so

4. A first principles investigation of mercuric iodide: bulk properties and intrinsic defects
We carried a theoretical investigation on the properties of mercuric iodide in the red tetragonal crystalline phase, and its respective intrinsic defects. Our calculations were performed using the ab initio spin-polarized full-potential linearized augmented plane wave method, and taking into account full atomic relaxation. The results on the structural, elec

5. Estudo in situ do perfil de concentração do soluto durante o processo de crescimento e dissolução de monocristal de alfa-HgI2 / In situ study of solute concentration profile during crystal growth and dissolution of alfha-HgI2
The solute concentration profile near to the crystal/liquid inter-face was studied during mercuric iodide crystal growth and dissolution with phase measurement by diffraction optical technique - "diffrasor". Its simple, sensitive to hydrodynamics phenomena and may be used either in macro or in micro-observations. With this technique we measured, for the firs
