Doping of predominantly cis polyacetylene with FSO2OOSO2F in SO2F2 solutions at low temperatures yields materials that possess apparently metallic electrical conductivities with, for example, σRT= 700 Ω–1 cm–1, increasing to a maximum of 800 Ω–1 cm–1 at 150 K before declining to 640 Ω–1 cm–1 at 4·2 K.
The results of an experimental study of the infrared absorption of the ${(\mathrm{CH})}_{x}$ system, lightly doped ( 0.1%) with acceptors and donors, are presented. Additional a...
Hydrogen desorption kinetics from monohydride and dihydride species on crystalline-silicon surfaces were measured using transmission Fourier-transform infrared (FTIR) spectrosco...
The results of an electron spin resonance (ESR) study of trans-polyacetylene, before and after doping with AsF5, are reported. The undoped polymer exhibits a Lorentzian line (g=...
Polycrystalline black phosphorus has been produced by the Bridgman method of combined temperature and pressure and found to be p type with room-temperature resistivity around on...
A broad organic-inorganic series of hybrid metal iodide perovskites with the general formulation AMI3, where A is the methylammonium (CH3NH3(+)) or formamidinium (HC(NH2)2(+)) c...
