[0002] In the environment of extremely low temperature and strong magnetic field, the current two methods of electric transport and thermoelectric transport are usually used to study the movement of quasiparticles under external stimulation to obtain the properties of materials. The use of acoustic and electric transport to study the intrinsic properties of materials can add a new measurement method to physics research to obtain more information on the properties of materials.

[0003] The use of acoustic-electric transport to study materials usually requires the introduction of multi-dimensional radio frequency signals. However, in the environment of extremely low temperature and strong magnetic field, the introduction of multi-dimensional radio frequency signals has always faced many adjustment problems: on the one hand, since the transmission of GHz radio frequency signals needs to be transmitted through semi-rigid coaxial lines or flexible coaxial lines with very thick diameters, the traditional connection method cannot achieve the angle rotation of the sample; on the other hand, the low temperature and strong magnetic field measurement environment is extremely narrow, and there is not enough space to leave a turning radius for the radio frequency transmission line to support its bending and twisting, and at low temperatures, high-frequency coaxial lines are harder and more difficult to rotate. Based on the above problems, it can be seen that the existing structure has poor applicability in the environment of extremely low temperature and strong magnetic field, and is greatly limited when conducting material research.

[0029] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0030] In metals and semiconductors, the directed motion of electrons can be generated by applying an electrical bias or a temperature gradient. The acceleration of electrons is hindered by scattering with impurities or phonons, resulting in an equilibrium state with a finite potential drop in the system. This transport process provides a simple and flexible way to probe electronic states and has become one of the most important experimental techniques since the early days of condensed matter physics. The introduction of a magnetic field in the transport further produces the magnetoresistance effect and the Hall effect, which provide a method for accurately evaluating the carrier concentration and the induced magnetic field, which is widely used in the semiconductor industry. In addition, in high-mobility systems, oscillations can be detected in the resistivity at low temperatures due to the formation of discrete Landau levels. It allows direct measurement of Fermi surface properties such as the Fermi wave vector, quasiparticle effective mass, and quantum lifetime. In recent years, the investigation of quantum oscillations has played a crucial role in the study of two-dimensional electronic systems and topological materials. For transport experiments, different types of excitations lead to different responses of quasiparticle motion. The electrical bias affects only charged carriers and leads to a shift of the entire Fermi surface and a momentum displacement. In contrast, the temperature gradient leads to entropy flow and directed thermal migration of charged and charge-neutral quasiparticles. The ratio of the electronic contribution of electrical to thermal conductivity can be used to diagnose non-Fermi liquid properties beyond the Wiedemann−Franz law. Therefore, combining multiple transport methods, including electrical, thermal, and thermoelectric conductivity, can help explore different aspects of material properties in a more diverse way.

[0031] Transmission detects the movement of quasiparticles in response to external stimuli. In addition to the well-known electrical and thermoelectric transmission, the acoustic-electric transmission caused by traveling sound waves has rarely been explored. Therefore, in the environment of extremely low temperature and strong magnetic field, the use of acoustic-electric transmission to study the intrinsic properties of materials can add a new measurement method to physics research to obtain more information about the properties of materials. The existing device structure cannot realize the angle measurement of material samples in the environment of extremely low temperature and strong magnetic field, resulting in great limitations in material research. Compared with the existing device structure, the corner device supporting radio frequency transmission proposed in this application can realize the angle measurement of material samples in the environment of extremely low temperature and strong magnetic field while introducing radio frequency signals. This adjustable angle acoustic-electric measurement method, as a new detection method, has opened up a new measurement dimension for material research, thereby obtaining more intrinsic physical property information of materials.
