Narrow Zero Mode in Organic Massless Dirac Electron System $\alpha$-(BEDT-TTF)$_2$I$_3$
We investigated the interlayer magnetoresistance in an organic massless Dirac electron system $\alpha$-(BEDT-TTF)$_2$I$_3$ under pressure. We experimentally demonstrate that the width of the zero mode owing to carrier scattering is much narrower than that of the other Landau levels.
