Thermoelectric and Thermal Transport Properties in Sumanene Crystals

Comprehensive Understanding and Controlling the Defect Structures: An Effective Approach for Organic-Inorganic Hybrid Perovskite-Based Solar-Cell Application

“…In this case, theoretical works are not enough to understand defect structures at the grain boundary. In this review, the authors suggest several measurements to understand (1) atomic structure, (2) electronic structure of defects, and (3) their trap states at the grain boundary using Grazingangle Incident X-ray Diffraction (GIXD; Park et al, 2018), high-resolution Photoelectron Spectroscopy (PES; Kojima et al, 2018) with synchrotron radiation, and Field-Effect Thermally-Stimulated-Current (FE-TSC; Kojima et al, 2018), respectively. GIXD will provide a finely detailed structure of polycrystalline OHP thin film from the surface to bulk included with the grain boundary.…”

Dielectric response of 1,1-difluorosumanene caused by an in-plane motion

“…1b). 17 In particular, 2 forms unidirectionally arranged p-stacking columns in the solid state that show an anisotropic electron mobility along the stacking column 18 and a large Seebeck co-efficient at right angles to the column; 19 moreover, 2 can operate as a liquid-crystalline mesogen. 20 This background clearly shows that the sumanene skeleton has considerable potential as a core for functional materials.…”

Thermal conductivity of benzothieno-benzothiophene derivatives at the nanoscale

“…The BTE approach is known to be far much prohibitive in terms of computational cost than MDbased techniques. Thus, κ of a few molecules ( pentacene, C 60 , PCBM, H 2 Pc, TPD,…) [30][31][32][33][34][35][36][37][38] have been essentially calculated by various methods belonging to the "MD-class" in order to estimate the anisotropy of κ along the long axis of the molecules versus in the perpendicular intralayer directions.…”
