摘要：

Graphite-bromine produces a tensile stress (up to about 3 MPa) along the c-axis upon heating by the passage of an electric current (with a current density of up to about 5 multiplied by 10**5 A/m**2). This electromechanical effect was reversible and allowed electromechanical switching. The stress increase started at about 100 degree C upon heating. The c-axis electrical resistivity increased and then decreased upon heating, and increased and then decreased upon cooling, when the sample was under mechanical constraint from expansion. These effects are attributed to the initiation of intercalate bubble formation.
