CADMIUM ARSENIDE Meaning and
Definition
-
Cadmium arsenide is a chemical compound with the formula Cd3As2. It is composed of the elements cadmium (Cd) and arsenic (As), and it belongs to the class of binary compounds known as arsenides. Cadmium arsenide is a semiconductor material with unique electronic properties, making it of significant interest in various fields, particularly in solid-state physics and electronic device manufacturing.
In terms of its physical characteristics, cadmium arsenide typically exists as a dark gray, crystalline solid. It has a cubic crystal structure and can be grown as single crystals, allowing for precise studies of its properties. The compound is insoluble in water and has relatively high thermal stability.
From an electronic perspective, cadmium arsenide exhibits semimetallic behavior, which means that its energy band structure resembles both metals and semiconductors. This makes it highly suitable for various applications, such as high-speed transistors, solar cells, and thermoelectric devices. Moreover, cadmium arsenide has exceptional electronic mobility, enabling the transport of charge carriers with minimal scattering, a property that is crucial in achieving high-speed electronic devices.
It's important to note that cadmium arsenide contains toxic elements: cadmium and arsenic. The compound should be handled with caution and appropriate safety protocols should always be followed to minimize any potential health and environmental risks associated with its use.
Etymology of CADMIUM ARSENIDE
The word "cadmium" is derived from the Latin word "cadmia", which refers to a zinc ore. The term "arsenic" comes from the Greek word "arsenikon", which means yellow orpiment. When combined, "cadmium arsenide" represents the chemical compound composed of the element cadmium (Cd) and the element arsenic (As).
