What are the examples of binary II-VI compound semiconductors?

Group II-VI Compound Semiconductors

  • Cadmium selenide (CdSe)
  • Cadmium sulfide (CdS)
  • Cadmium telluride (CdTe)
  • Zinc oxide (ZnO)
  • Zinc selenide (ZnSe)
  • Zinc sulfide (ZnS)
  • Zinc telluride (ZnTe)

What is the meaning of Ii-Vi?

The Roman numerals “II-VI” refers to group II and group VI of the Periodic Table of Elements. By chemically combining elements from these groups, II-VI produced the infrared optical crystalline compounds: Cadmium Telluride (CdTe), Zinc Selenide (ZnSe), Zinc Sulfide (ZnS) and Zinc Sulfide MultiSpectral (ZnS MS).

Which is the example of compound semiconducting material?

Apart from silicon, there are compound semiconductors that combine Group III and V elements and Group II and VI elements. For example, GaAs, InP, InGaAlP, etc. have been conventionally used for high-frequency devices and optical devices.

Why is cadmium sulfide a semiconductor?

Cadmium sulfide is mainly used as a pigment owing to its good thermal stability, light and weather fastness, chemical resistance, and high opacity. Other applications of cadmium sulfide are listed below: Photoresistors….

Chemical Properties
Crystal Structure Hexagonal, Cubic
Lattice Constants a=4.160 Å c=6.756 Å

What are Ii-Vi materials?

II–VI semiconductors, ME (M = Cd, Zn, Hg; E = S, Se, Te), include materials such as cadmium selenide (CdSe), cadmium sulfide (CdS), cadmium telluride (CdTe), zinc selenide (ZnSe), zinc sulfide (ZnS), and zinc telluride (ZnTe). II–VI NCs are well known as QDs with size-tunable absorption and emission.

WHAT IS II-VI chord progression?

in a ii-V-I, the lower case ii denotes a minor chord starting on the second degree of a major scale, the upper case V denotes a major chord starting on the 5th degree of a major scale and the upper case I denotes a major chord starting on the 1st degree of a major scale.

What are semiconductors made of?

The most used semiconductor materials are silicon, germanium, and gallium arsenide. Of the three, germanium was one of the earliest semiconductor materials used. Germanium has four valence electrons, which are electrons located on the outer shell of the atom.

What are compound semiconductor used in?

Compound semiconductors will underpin the Internet of Things by virtue of their greater power efficiency (for battery-powered devices) and optical properties (in sensors for new imaging techniques implemented in connected cars, healthcare, and industrial applications).

What are semiconductors examples?

Examples of Semiconductors: Gallium arsenide, germanium, and silicon are some of the most commonly used semiconductors. Silicon is used in electronic circuit fabrication and gallium arsenide is used in solar cells, laser diodes, etc.

Which one of the following are the properties of compound semiconductors?

At absolute zero, semiconductors are perfect insulators, The density of electrons in conduction band at room temperature is not as high as in metals, thus cannot conduct current as good as metal. The electrical conductivity of semiconductor is not as high as metal but also not as poor as electrical insulator.
