On-Chip THz Time-Domain Spectroscopy Sensor with Adjustable Sample Interaction by a Daughterboard

International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz), pp. 1–2

Abstract

In this study, we use a low-loss on-chip Terahertz (THz) sensor to measure conductance properties of metal thinfilms and two-dimensional (2D) materials. The sensor has a coplanar strip (CPS) transmission line that creates a highly confined THz field in a transversal direction. The field interacts longer with the sample as it travels along the CPS line. We also use a detachable sample carrier film (a daughterboard) that can be easily replaced. This makes the sensor reusable and adjustable. The length of the daughterboard can change the interaction of the THz signal with the sample. Our low-loss on-chip THz sensor platform can analyze 2D materials sensitively and compactly which is important for future application in small cryostat chambers.
