The fermi level is the surface of fermi sea at absolute zero where no electrons will have enough energy to rise above the surface. The fermi level lies between the valence band and conduction band because at absolute zero temperature the electrons are all in the lowest energy state. A semiconductor is a solid that is defined as having its fermi level (chemical potential) in a band gap of the electronic structure of the solid, which is not too large compared to the thermal energy, so that, according to the fermi distribution, at room temperature you have a significant number of electrons and/or holes in the conduction and. The electrical conductivity of the semiconductor depends upon the total no of electrons moved to the conduction band from the valence band.
Fermi energy is the difference highest occupied state and lowest occupied state at 0k. Fermi level is a kind of measure of equilibrium electronic energy of a solid material. There are bands crossing the fermi level, so the material is metallic. The fermi level is the energy separating occupied states of the valence band from empty states of the conduction band at the absolute temperature t=0 kelvin.

Employers and employees are often conflicted over sick leave and annual leave arrangements. Employers may not know how to deal with payroll issues, especially when employees are absent from work due to mandatory quarantine. Should employers allow staff to take full pay, ⅘ pay, or no pay leave for such circumstance? It's not worthwhile if both sides end up in court due to wrong leave pay calculation. 1. What is sick leave allowance? The daily amount of sick leave allowance is equal to ⅘ of the average daily wage (ADW) earned by the employee during the 12 months preceding the day of sick leave or the first day of sick leave if the number of sick days is more than one consecutive day. If the employment period of the employee is less than 12 months, the shorter period will be counted. 2.How exactly should sick leave allowance be calculated? When will it be paid? In calculating the ...
