S-Scheme Heterojunction Photocatalyst [PDF]
Chem, 2020 Summary The significance of photocatalysts is unquestionable, and scientists are devoted to improving their photocatalytic efficiency. To solve the high recombination rates of photogenerated electron-hole pairs and their low reduction and oxidation abilities in a single photocatalyst, heterojunction manipulation is urgently required.

Graphene nanoribbon heterojunctions [PDF]
Nature Nanotechnology, 2014 Despite graphene's remarkable electronic properties, the lack of an electronic bandgap severely limits its potential for applications in digital electronics. In contrast to extended films, narrow strips of graphene (called graphene nanoribbons) are semiconductors through quantum confinement, with a bandgap that can be tuned as a function of the ...

Silicon Heterojunction Microcells
ACS Applied Materials & Interfaces, 2021 We report the design, fabrication, and characterization of silicon heterojunction microcells, a new type of photovoltaic cell that leverages high-efficiency bulk wafers in a microscale form factor, while also addressing the challenge of passivating microcell sidewalls to mitigate carrier recombination. We present synthesis methods exploiting either dry

Diamond / SiC heterojunctions [PDF]
2016 12th Conference on Ph.D. Research in Microelectronics and Electronics (PRIME), 2016 Diamond and SiC are wide bandgap (WBG) materials which can be used to fabricate high power devices with improved performance. The combination of these materials into one single device is expected to bring some benefits, like a better thermal management with a corresponding increase in the operating power.

Time dependent behavior of a localized electron at a heterojunction boundary of graphene [PDF]
, 2010 We develop a finite-difference time-domain (FDTD) method for simulating the dynamics of graphene electrons, denoted GraFDTD. We then use GraFDTD to study the temporal behavior of a single localized electron wave packet, showing that it exhibits optical ...
