TCAD Analysis of Silicon-Germanium (SiGe) Based Back-Contact Back-Junction (BC-BJ) Solar Cell-an Alternative for Silicon Based Cells

Pandey R., Chaujar R., Delhi Technological University, IN

In this work, an ultra-thin, Back-Contact Back-Junction (BC-BJ) Crystalline Silicon-Germanium (SiGe) solar cell device structure called BC-BJ c-SiGe solar cell has been proposed. The results, are compared with conventional BC-BJ silicon cell. SiGe is used [...]

Inducing Aromaticity Patterns and Tuning the Electronic Transport of Graphene Nanoribbons via Edge Design

Fias S., Martin-Martinez F.J., Van Lier G., De Proft F., Geerlings P., Free University Brussels (VUB), BE

Tuning the band gap of graphene nanoribbons (GNR) by chemical edge functionalisation is a promising approach towards future electronic devices based on graphene. The band gap is closely related to the aromaticity distribution and therefore [...]

Electronic Structure and Band Gap Engineering of ZnO-based Semiconductor Alloy Films

Liu P-L, Shao P-T, National Chung Hsing University, TW

We conduct first-principles total-energy density functional calculations to study the band structures and atomic structures in ZnO and Zn0.5M0.5O alloys using the planewave projector augmented-wave (PAW) method with the Heyd-Scuseria-Ernzerhof (HSE) hybrid functional. We find [...]

Surface Plasmon Grating Coupled Emission from Organic Emitter for Detecting Refractive Index Variation

Chiu N.-F., Lee J-H., Lin C-W, National Taiwan Normal University, TW

We demonstrated the surface plasmon grating coupled emission (SPGCE) from photo-excited organic layer covered with metal thin film on the corrugated substrate. Directional emissions corresponded to the resonant condition of surface plasmon modes on the [...]
