2023年11月2日 · In this work, we address this problem by performing high-resolution scanning tunneling microscopy/spectroscopy (STM/STS) experiments at 340 mK in the prototype 1T/1H-heterostructure and...

2022年4月20日 · Here we show that the Pb intercalation in the charge-density-wave-driven narrow-electronic-band system 1T-TaS2 induces a transition from the insulating gap to a sharp Kondo resonance in the ...

2021年1月25日 · We revisit the theory of the Kondo effect observed by a scanning-tunneling microscope (STM) for transition-metal atoms (TMAs) on noble-metal surfaces, including $d$ and $s$ orbitals of the TMA, surface and bulk conduction states of …

The development of low-temperature scanning tunneling microscopes (STM) operating under ultrahigh vacuum (UHV) conditions has provided new opportunities for investigating locally the electronic structure at surfaces.

2018年9月25日 · In the scanning tunnelling microscope, the many-body Kondo effect leads to a zero-bias feature of the differential conductance spectra of magnetic adsorbates on surfaces. The intrinsic line shape of this Kondo resonance and its temperature dependence in principle contain valuable information.

2021年11月12日 · We theoretically analyze a state-of-the-art experimental method based on a combination of electron spin resonance and scanning tunneling microscopy (ESR-STM), to directly probe the spin fluctuations in the Kondo effect.

2017年6月30日 · By controlling the distance between the Fe 2+ ion and the Au substrate through approaching an STM tip to the ion, we tune the Kondo couplings over the SOI, and demonstrate the spectral...

2022年2月28日 · The spin-polarized scanning tunneling microscope (SP-STM) has served as a versatile tool for probing and manipulating the spintronic properties of atomic and molecular devices with high precision. The interplay between the local spin state and its surrounding magnetic environment significantly affects the transport behavior of the device.

2013年11月14日 · Conduction measurements of magnetic systems at low temperature, like the present study of 3d transition metal MePc on Ag (100) are closely intertwined with a phenomenon known as the Kondo effect. Essentially it is a coupling of the conduction electrons of a metal to a...
