Patent ID: 11069507

Abstract:
A sample carrier for in situ transmission electron microscopy (TEM) has a dielectric substrate with a conductive layer that forms a coplanar waveguide. The coplanar waveguide has a first and second leads formed by the conductive layer. The first lead is between an adjacent pair of second leads and is spaced from the second leads by a respective gap. The coplanar waveguide is configured to transmit an electrical signal to a specimen held by the sample carrier, in particular, an electrical signal having a frequency in the radio-frequency (RF) regime (3 kHz-300 GHz), for example, up to 100 GHz. The sample carrier may be mounted to a TEM sample holder, which supports the sample carrier within a vacuum chamber of the microscope and provides electrical connection between the leads of the sample carrier and an RF source external to the vacuum chamber.
