Scientists are striving to discover new semiconductor materials that could boost the efficiency of solar cells and other ...

For the future, the researchers say that the same Fermi-level engineering approach can be readily extended to other semiconductors with doping issues, such as III-nitrides, oxides, diamond, HgCdTe etc ...

Dr. Min-Chul Park added, "2D semiconductor-based optoelectronic devices that overcome the challenge of Fermi level pinning will have a significant impact across industries that demand ultra ...

By applying a voltage pulse to the ferroelectric, the Fermi level of the graphene shifts, thus modifying the current direction. Professor Yoo stated, "This study lays the groundwork for addressing the ...

The Fermi level is shifted down as the particle size increases and is pinned on an absolute energy scale considering the band alignment at AlAs/GaAs/InAs interfaces, offering insights into the ...

Professor Soon-Yong Kwon in the Department of Materials Science and Engineering and the Graduate School of Semiconductor Materials and Devices Engineering at UNIST, in collaboration with Professor ...

If a material is an insulator, that means that its Fermi level is sitting inside a wide band gap, and its electrons will not be able to give you any current. Metals, on the other hand, have one or ...

WSe 2 is an ambipolar material, which means the Fermi level shifts between the valence and conduction bands in the presence of an applied field. Thus, the same material can conduct either electrons or ...
