What are II-VI semiconductors?
II-VI semiconductor compounds are compounds composed of a metal from either group 2 or 12 of the periodic table (the alkaline earth metals and group 12 elements, formerly called groups IIA and IIB) and a nonmetal from group 16 (the chalcogens, formerly called group VI).
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).
What is a compound semiconductor?
Compound semiconductors are semiconductors that are made from two or more elements. Silicon is made from a single element, and therefore is not a compound semiconductor.
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 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.
Where is II-VI Incorporated located?
Saxonburg, Pennsylvania
Headquartered in Saxonburg, Pennsylvania, the Company has research and development, manufacturing, sales, service, and distribution facilities worldwide.
Why are compound semiconductors used?
The compound semiconductor materials allow monolithic integration of optoelectronic devices such as lasers, light-emitting diode (LEDs), and photodiodes with micromechanical structures. This enables light generation, transmission, modulation, and detection on a single chip.
What are compound semiconductors used for?
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 cadence is Ii Vi?
In jazz, a cadence is often referred to as a turnaround, chord progressions that lead back and resolve to the tonic (for example, the ii-V-I turnaround). Turnarounds may be used at any point and not solely before the tonic. Half-step cadences are common in jazz if not cliché.
How do I use II-VI?
(add the roman numerals on screen) The II V I is a chord progression that starts on II (Dm7) goes to V(G7) and resolves to (I) Cmaj7. So the II V I is a short progression to take us to the C major.

What are elemental and compound semiconductors?
The elemental semiconductors are those composed of single species of atoms, such as silicon (Si), germanium (Ge), and tin (Sn) in column IV and selenium (Se) and tellurium (Te) in column VI of the periodic table. There are, however, numerous compound semiconductors, which are composed of two or more elements.
