Once all the atoms coalesce to form a crystal, these molecular orbitals overlap and broaden, leading to the energy bandstructure with gaps and allowed energy bands. The mostly lled valence bands are formed primarily from the bonding orbital states, while the unlled conduction band is primarily associated with the antibonding states.
For semiconductors, one is typically worried about the bandstructure of the conduction and the valence bands only.
Electronic band structure calculation methods can be grouped into two general categories . In general, these methods utilize a variational approach to calculate the ground state energy of a many-body system, where the system is dened at the atomic level.
Today, calculations are performed using thousands of atoms but are computationally expensive, sometimes requiring massively parallel computers. In contrast to ab initio approaches, the second category consists of empirical methods, such as the Orthogonalized Plane Wave OPW , tight-binding  also known as the Linear Combination of Atomic Orbitals LCAO method , the k p method , and the local , or the nonlocal  empirical pseudopotential method EPM.
These methods involve empirical parameters to t experimental data such as the band-to-band transitions at specic high-symmetry points derived fromoptical absorption experiments. The appeal of these methods is that the electronic structure can be calculated by solving a one-electron Schr odinger wave equation SWE.

Thus, empirical methods are computationally less expensive than ab initio calculations and provide a relatively easy means of generating the electronic band structure.The mostly lled valence bands are formed primarily from the bonding orbital states, while the unlled conduction band is primarily associated with the antibonding states.
Computational electronics, as a part of the general Technology Computer Aided Design TCAD field, has become increasingly important as the cost of semiconductor manufacturing has grown exponentially, with a concurrent need to reduce the time from design to manufacture.
Numerous exercises and projects were derived from this course and have been included. Guan, D. The valence band states are linear combinations of p-like orbitals.
Highlighting the need for quantum transport approaches, it describes various quantum effects that appear in current and future devices being mass-produced or fabricated as a proof of concept. Final state after scattering -- 6. Hydrodynamic model -- 4.
