Rubrene charge-carrier mobility

The simulated current-voltage characteristic (Fig. 8.30) corresponds roughly to the experimentally-determined characteristics for rubrene and tetracene crystals in the non-ohmic range (Fig. 8.27). For the ultrapure tetracene crystals, the values fx 1 cm /Vs for the mobility at room temperature and Nt<5-10 cm , Et 700 meV for the density and the depth of the charge-carrier traps were found [37].
