To say not exactly: effective mass describes the effects of all the internal forces exerted on an electron in a crystal.learner@123 said:how it depends on the crystalline nature of polymer.
Is there any average value defined for polyethylene .hokhani said:To say not exactly: effective mass describes the effects of all the internal forces exerted on an electron in a crystal.
That's true ,but very small leakage current flows at high field ratings (KV/mm) .For that i want effective mass.DrDu said:I didn't know that in polyethylene you have mobile charge carriers at all. It is a very good insulator.
The effective mass of an electron in polyethylene refers to the mass that an electron appears to have when moving through the material. It is a measure of the electron's response to an applied electric field.
The effective mass of an electron in polyethylene is determined through experimental measurements, such as Hall effect measurements or cyclotron resonance. The results are then compared to theoretical calculations to verify accuracy.
The effective mass of an electron in polyethylene can be affected by the material's crystal structure, temperature, and the presence of impurities or defects. External factors such as electric and magnetic fields can also influence the effective mass.
The effective mass of an electron in polyethylene is important because it provides insight into the material's electronic properties. It can also affect the material's electrical conductivity, which is crucial for applications in electronics and energy storage.
No, the effective mass of an electron in polyethylene is not a constant value. It can vary depending on the material's properties and external conditions. In some cases, it may even have an anisotropic nature, meaning it can vary in different directions within the material.
