Physics Spl

In solid-state physics, the free electron model is a simple model for the behaviour of valence electrons in a crystal structure of a metallic solid. It was developed principally by Arnold Sommerfeld who combined the classical Drude model with quantum mechanical Fermi-Dirac statistics and hence it is also known as the DrudeSommerfeld model.
The free electron empty lattice approximation forms the basis of the band structure model known as nearly free electron model. Given its simplicity, it is surprisingly successful in explaining many experimental phenomena, especially
The WiedemannFranz law which relates electrical conductivity and thermal conductivity;
The temperature dependence of the electron heat capacity;
The shape of the electronic density of states;
The range of binding energy values;
Electrical conductivities;
Thermal electron emission and field electron emission from bulk metals.

A candidate with a Bachelors degree in Physics can apply to different jobs through the test conducted by following organizations in the government sector
Union Public Service CommissionStaff selection commissionIndian Forest ServicesPublic sector BankState PCSIndian Defense services etc.
Central Government Jobs after B.Sc. Physics
Those candidates who are looking for a career in government sector organizations need to update themselves with the notification of exams conducted by the UPSC, SSC etc as the test conducted by these organizations opens way for candidates to enter into various departments. They need to prepare these exams with full dedication and with systematic planning so that they will be successful in their career. UPSC conducts exam for civil posts like IFS, IPS, and IAS in the government sector. These include:
Tax AssistantStatistical InvestigatorGrade III & Compiler ExamCombined Higher SecondaryCombined Graduate Level Exam etc.
