Semiconductor Photodetectors

Ingram 出版
2024/09/04 出版

The exponential increase of the Internet of Things (IoTs) has revolutionized lives, but it has also resulted in massive resource consumption and environmental pollution. In conjunction with Green IoTs (GioTs), there is a parallel effort to create highly sensitive devices by device design to conserve power. Furthermore, numerous applications require deciphering information from very weak optical signals, such as from radiation, medical imaging, industrial non-destructive testing, quantum technologies, astronomy, and various other such routine measurements. It is necessary to design photodetectors with high photosensitivity using various technological innovations to reduce the noise level, such as with two inversely directed barriers, as proposed by the authors, in which the currents of devices mutually compensate each other and create low dark current with high photosensitivity thresholds. The implementation of internal amplification of photocurrents in them can provide high photosensitivity. The book presents the mechanism for the injection amplification of the photocurrent in devices based on cadmium telluride and silicon with a high-resistance sublayer, as well as the study of creating highly sensitive devices, that are resistant to radiation of optical and X-ray ranges of electromagnetic waves. Particular attention is drawn to the mutual compensation process for photocurrents arising in opposite potential barriers covering the layer during longitudinal absorption of radiation in the sublayer. Using structures on the base cadmium telluride and silicon, as an example, the phenomenon of a change in the sign of the spectral photocurrent and the possibilities of wave measurement is provided by this phenomenon. Photoelectronic processes occurring in these semiconductor structures are investigated, and expressions are obtained that relate the parameters of optical radiation and the structure. The algorithm developed using these expressions is based on a new spectral analysis mechanism, which is implemented to prepare inexpensive, reduced dimensions with the need for less materials, and energy-intensive devices. All this is considered in the context of solving urgent problems of quantitative remote identification of the components of an optically transparent medium. The global spectral analysis market is focused on the development of semiconductor photodetectors with spectral-selective sensitivity for spectral analysis. The use of such a photodetector in spectrometry will eliminate the use of opticalmechanical systems due to the new physical principle used in it and will ensure high resolution and reliability of spectrum recording. As environmental threats become increasingly unpredictable, there is also a growing need to develop remote spectral analysis, identification, and assessment of substances in air, water, and food, assessment of the effects of substances on humans, animals, and vegetation, and detection and elimination of pollution sources. Here, the spectral analysis of the electromagnetic radiation transmitting the information from the object with the help of primary sensors is essential.

Teaching the visually impaired from a multi-sensory perspective

Ingram 出版
2024/09/03 出版

For some years now, the transfer of students with special needs from special education to mainstream education has been taking place in Brazil. However, schools and educators have not been prepared for this change, and physical and attitudinal barriers to inclusion still prevail. It is believed in this research that one of the ways to solve this problem is to work on the inclusion of blind students through experimentation and digital teaching resources. In the scientific literature, there are already several teaching resources that have been created or adapted, but there is still a lot to be done, especially for students with special needs. Considering Vygotsky's theory, in which students with special needs should learn the same content with the same degree of demand as others, and using a multisensory methodology, we developed teaching material consisting of a didactic sequence and adapted materials with the aim of facilitating the teaching-learning process of the chemical reactions content for students with or without sight problems.

Chemical Clusters from Skeletal Numbers to Capping Indices

Ingram 出版
2024/08/27 出版

The recent discovery of skeletal numbers made it possible to analyze and categorize hundreds of chemical clusters. In the process, the categorization parameter K*= DzCy where z+y=n (the total number of skeletal elements) was also discovered. In conventional clusters, the skeletal elements in a cluster can be distributed into two shells namely the D and C shells. The D shell follows the 14n capping series while the C shell follows the 12n capping series. On close scrutiny and analysis of cluster series, an equation for determining cluster valence electrons was developed. The equation is given by VE=14z+2+12y for transition metal clusters. Since, VE=VF which can be calculated from the cluster formulas, the values of z and y can easily be calculated as VF= 14z+2+12y. In actual fact these two equations can be simplified to generate a much simpler equation VF-12n=2z+2. Hence, knowing VF, and n, the value of z and subsequently that of y can readily be obtained. Thus, K*=DzCy can be derived without using skeletal numbers. From K*, cluster number K and cluster valence electrons as well as constructing isomeric shapes can be generated.

Qualitative Analysis of Zintl Ions

Ingram 出版
2024/08/26 出版

The recent discovery of skeletal numbers enables us to determine the partial and/or the total number of the chemical linkages found in a cluster formula.The isomeric shapes of chemical clusters strictly obey the natural law K=n+t where K is given the name CLUSTER NUMBER and represents the total linkages in a chemical cluster, n represents the primary linkages and t represents the secondary linkages. It was also discovered that K has a double meaning. Its value corresponds to the number of ELECTRON PAIRS it requires so that each of its skeletal elements attains a NOBLE GAS configuration. The formula K=n+t has also been found to be a very powerful instrument for the construction of isomeric shapes of chemical clusters. Once the cluster formula has been constructed in line with the law K=n+t, it does reflect the cluster formula's content showing all the skeletal elements in the cluster as well as their skeletal valances, charges and any ligands present. Therefore, we can regard the lines drawn in shapes of isomeric clusters as not just geometrical lines, but rather as "LIVE WIRES'' carrying cluster valence electrons to and from the neighboring skeletal elements.
