The OE1022 Lock-in Amplifier offers superior performance and ease of use for scanning tunneling spectroscopy measurements.
The OE1022 lock-in amplifier measures signal-to-noise ratios significantly better than instruments of international counterparts.
The performance of the OE1022 lock-in amplifier is stable, and its convergence speed and measurement accuracy in small ranges are significantly better than those of a well-known international brand.
In September 2023, Associate Professor Guorui Chen's team at the Key Laboratory of Artificial Structures and Quantum Regulation of the Ministry of Education, Shanghai Jiao Tong University, collaborated with Jeil Jung's team at Seoul National University, Korea, to publish an article in Nature titled 'Spontaneous broken-symmetry insulator and metals in tetralayer rhombohedral graphene'. The article demonstrates that crystalline multilayer graphene is an ideal platform for studying various symmetry breaking driven by Coulomb interactions.
In 2022, Prof. Xiaomu Wang and Prof. Yi Shi from Nanjing University published an article in Nature Communications titled 'Quantum Criticality of Excitonic Mott Metal-Insulator Transitions in Black Phosphorus.' The article reports on the spectroscopy and transport phenomena of excitonic Mott metal-insulator transitions in black phosphorus. Photoexcitation continuously modulates the interactions between electron-hole pairs. Fourier transform photocurrent spectroscopy was used to measure the integrated phase diagrams of the electron-hole states at different temperatures and electron-hole pair density parameter spaces as a probe.
