Many efficient light-emitting devices and photodetectors are based on semiconductors with, respectively, a direct or indirect bandgap configuration. The less known pseudodirect bandgap configuration ...

Recently, the group of professor ZHANG Yongsheng from the Institute of Solid State Physics, Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences (CAS) identified the orbital ...

Researchers at Lund University, Sweden, have grown single continuous GaAs nanowires consisting of segments of pure wurtzite and zincblende phases. Using photoluminescence spectroscopy, they found that ...

Bandgap refers to a region of an element’s crystal’s electronic band structure through which electrons can’t pass. Also referred to as an energy gap, bandgap is a concept in solid-state physics and ...

Gapless semiconductors are a very new class of solids in which the conduction and valence bands meet at the Fermi level. As a result of this structure, the threshold energy needed for electrons to ...

An international research team has developed a new intermediate band solar cell (IBSC) design that includes a quantum ratchet (QR) semiconductor nanostructure. This new element reportedly enables ...

In semiconductor physics, the flat band potential is a critical parameter that influences the properties and behavior of semiconductors in contact with other materials, such as electrolytes or p-n ...

Many modern electronic devices we use daily owe their existence to the process of semiconductor doping. Doped semiconductors are the result of careful modifications ...
