GaP in an indirect band gap material
Bandgap
Silicon has a larger bandgap energy than germanium, which contributes to higher junction potentials and ability to operate at higher temperatures.
Indirect bilirubin travels through the blood stream to the liver. Indirect bilirubin does not dissolve in water until it reaches the liver.
Direct material are those material which are easily identified, conveniently measured and directly charged to the cost of production. It is also part of the finished product. Example of direct materials are Timber in cases of furniture making, Leather in case of shoe making, cotton in case of shirt making etc. Indirect Material are those materials which cannot be conveniently identified & allocated to the cost centre or cost unit. It does also not form part of the finished product. Example of indirect material are bottom in case of shirt making, Thread in case of shirt making, pin & paste in case of furniture making etc.
Indirect is used to test for ANTIBODIES and direct is used to test for ANTIGENS. For example, Indirect ELISA is used to test for HIV antibodies.
Bandgap
becoz Si and Ge are indirect bandgap semiconductors. for lasing action direct bandgap semiconductors are required of the type In Ga As P
Would overhead include indirect materials and indirect labor?
Type 1 Semiconductors: The bandgap of one semiconductor is completely contained in the bandgap of the other one. In double heterostructure design carriers will be confined in the smaller bandgap material. this structure is used to form barrier/quantum well in Multi quantum well lasers and LEds Type II: like Type I The bandgap of the two materials overlap but the changes in the conduction and valence bands change sign. this type of materials do not use for light emiiting application as carriers can not be confined.
Indirect
One is indirect and one is direct!
raw material are indirect material
Because semiconductors such as silicon are indirect bandgap semiconductors, so some of the light energy is wasted as lattice vibrations (phonons).
Prime cost = direct materials + direct laborwhile conversion cost = direct labor + factory overhead( which includes indirect materials, indirect labor and other indirect costs
no
bandgap has an importance role for conduction.if bandgap is max,the conduction of electron is min. and vice-versa.hence we can say that the bandgap desides the conductivity of any material(may be metal or nonmetal)
The difference between direct purchase and indirect purchase is in what is purchased. Relating to raw materials, direct purchase is materials that go directly on a product and indirect is materials used to produce the product. Direct purchase can refer to purchasing products directly from manufacturers and indirect is purchasing through a middle person.
