"room temperature spin transport in thin film alpha-naphthyl diamine derivative (αNPD) molecules, a well-known material in OLEDs... fabricated photoconductive (enables spin transport control using visible light) thin molecular film of αNPD with spin diffusion length 62nm—a long distance for molecular materials but which is needed for practical applications... fabricated through thermal evaporation in vacuum... faster, smaller, super energy-efficient devices with little risk of overheating"
