Surface Studies

We have studied periodic orbit resonances (PORs) in order to probe the topology of the Fermi surface (FS) of the quasi-1D organic conductor ( TMTSF )2 ClO 4 and the quasi-2D organic conductors κ-( ET )2 Cu ( NCS )2 and κ-( ET )2 I 3. The FS of ( TMTSF )2 ClO 4 consists of a pair of weakly corrugated open sheets, while κ-( ET )2 Cu ( NCS )2 and κ-( ET )2 I 3 additionally possess warped cylindrical FS sections. In this paper, we review the POR technique for the straightforward case of ( TMTSF )2 ClO 4. We then report on a detailed study of the FS topology for κ-( ET )2 Cu ( NCS )2.
