Experimental Semiconductor Bandgap Databases

They have comprehensive tables for bandgaps, and the data is sorted by element.In summary, the person is looking for databases of experimental semiconductor bandgaps to compare to DFT calculations. They have already seen a Wikipedia list but are hoping for more extensive datasets. A recommendation is made for the CRC Handbook of Chemistry and Physics, which has comprehensive tables organized by element.

Related to Experimental Semiconductor Bandgap Databases

1. What is an experimental semiconductor bandgap database?

An experimental semiconductor bandgap database is a collection of data on the bandgap energy of various semiconductor materials. The bandgap energy is the minimum amount of energy required to excite an electron from the valence band to the conduction band, and it is an important parameter for understanding the electronic properties of a material.

2. How is the data in an experimental semiconductor bandgap database collected?

The data in an experimental semiconductor bandgap database is collected through various experimental techniques, such as optical spectroscopy, electrical measurements, and theoretical calculations. Researchers typically perform experiments on different semiconductor materials and record the corresponding bandgap energies, which are then compiled into a database.

3. What is the importance of experimental semiconductor bandgap databases?

Experimental semiconductor bandgap databases are important for researchers and engineers working in the field of semiconductor materials. They provide a comprehensive and reliable source of data for understanding the properties of different materials and for designing new electronic devices. These databases also help in the development of new theoretical models and in the validation of existing ones.

4. Are there any limitations to experimental semiconductor bandgap databases?

Like any scientific database, experimental semiconductor bandgap databases have their limitations. The data may not be complete or accurate for all materials, as it is dependent on the quality of the experiments and the techniques used. Additionally, the bandgap energy of a material can vary depending on its composition, crystal structure, and other factors, so the database may not provide a single, definitive value for a material.

5. How can I access an experimental semiconductor bandgap database?

Many experimental semiconductor bandgap databases are publicly available online, either through university or government websites. Some may require registration or payment for access. Additionally, many research papers and publications include the bandgap data for the materials studied, so these can also serve as a source of information for the database.
