Figure 1

Dissociation spectrum of a hole in an artificial molecule (solid line). Note the state reversal atd ~ 1.5 nm, implying a bonding-to-antibonding ground state transition. This never occurs for electrons in artificial or natural diatomic molecules, where the dissociation follows the pattern indicated by the dashed line. The insets are schematics of the molecular wavefunction orbital in the double quantum dot
