Schottky Barrier

Despite its promising characteristics in condensed matter physics, the triply-degenerate semimetal PtBi2 has been largely unexplored in practical applications, particularly in semiconductor technology. The main difficulties include a lack of empirical data on the integration of PtBi2 with existing semiconductor components and the need for innovative approaches to leverage its unique properties, such as high…

Hydrogen peroxide is used in many industries for a variety of purposes, including bleaching, sewage treatment, sterilization, and even as rocket fuel. Because hydrogen peroxide's byproduct is water, it has been lauded as a "green," environmentally friendly chemical, but a closer look at hydrogen peroxide's production process reveals a more complicated story. Problems like the amount of energy used for the…

A topological insulator, Bi2Te3, has been found to have spatially indirect spin-polarized excitonic states, opening the prospect of combining exciton and topological physics.

Developing low-cost and stable metal electrodes is crucial for mass production of perovskite solar cells (PSCs). As an earth-abundant element, Cu becomes an alternative candidate to replace noble metal electrodes such as Au and Ag, due to its comparable physiochemical properties with simultaneously good stability and low cost. However, the undesirable band alignment associated with the device architecture impedes…
