STRUCTURAL AND OPTOELECTRONIC PROPERTIES OF GE-RICH HYDROGENATED AMORPHOUS SILICON-GERMANIUM ALLOYS

In this work the structural and opto-electronic properties of rf sputtered germanium-rich hydrogenated amorphous silicon germanium alloys (a-SixGe1-x:H) are presented. It has been found that for x less-than-or-equal-to 0.1, the Si incorporation does not appreciably affect, either the density of localized states in the pseudo-gap, or the structural properties of the films. However the Tauc's optical gap shifts from 1.04 eV (x=0.0) to almost-equal-to 1.13 eV (x=0.1). A concomitant two orders of magnitude decrease of the dark conductivity is measured, whereas the photoconductivity remains essentially unchanged. In other words, the incorporation of small amounts of Si in the hydrogenated amorphous germanium (a-Ge:H) network produces a noticeable increase of the photosensitivity of the samples. These results are discussed in the framework of present models of amorphous semiconductor alloys.7642473247

Misdiagnosis of hearing loss due to ear canal collapse: A report of two cases

Collapse of the external auditory meatus during audiometry can lead to spuriously increased hearing thresholds : being obtained, particularly at high frequencies, and may simulate conditions such as noise-induced hearing loss, presbyacusis and retrocochlear pathology. Consequently, inappropriate investigations and management may be undertaken. Two patients with elevated thresholds secondary to ear canal collapse are described. The implications of initially failing to identify the true nature of their 'hearing losses' are highlighted and strategies to avoid such pitfalls are discussed

Large endolymphatic sac. A congenital deformity of the inner ear shown by magnetic resonance imaging

Fluctuant and progressive hearing impairment in a patient with a wide vestibular aqueduct has been called the 'large vestibular aqueduct syndrome'. Recently reports of magnetic resonance imaging (MRI) studies describe enlargement of the endolymphatic sac and duct in patients shown to have large vestibular aqueducts by computed tomography (CT). A patient with progressive deafness was shown to have borderline or slightly enlarged vestibular aqueducts by re-formatted sagittal CT. However, MRI in axial and sagittal planes gave a more satisfactory demonstration of both aqueduct and endolymphatic sac enlargement
