Imaging subsurface reflection phase with quantized electrons.
نویسندگان
چکیده
Lead quantum wells (QW) epitaxially grown on annealed Pb/Si(111) interface form a model system for the study of interactions between quantized electrons and adiabatically modulated boundaries. Tunnel spectra of this system reveal a previously unknown adiabatic shift of QW resonances due to lateral variations of the electronic reflection phase at the buried interface. With this effect, lateral distribution of the subsurface reflection phase can be probed, using scanning tunneling microscopy.

Design and fabrication of a high-Q near-field probe for subsurface crack detection
Non-destructive detection and evaluation of invisible cracks in metal structures is an important matter in several critical environments including ground transportation, air transportation and power plants. In this paper, a high-Q near-field Microwave probe is designed and fabricated using defected ground structures for surface and subsurface crack detection in metal structures. For this purpos...
متن کاملA closer look at rock physics models and their assisted interpretation in seismic exploration
Subsurface rocks and their fluid content along with their architecture affect reflected seismic waves through variations in their travel time, reflection amplitude, and phase within the field of exploration seismology. The combined effects of these factors make subsurface interpretation by using reflection waves very difficult. Therefore, assistance from other subsurface disciplines is needed i...
متن کاملPhase and temporal measurements in semiconductor quantum structures
A short overview is presented on measurements of phase evolution and temporal behavior of electrons in mesoscopic systems. Since ubiquitous conductance measurements provide only limited information about a system (its transmission coefficient), the complex values of all elements of the scattering matrix (transmission and reflection amplitudes), measured via interference experiments, might shed ...
متن کاملNontrivial quantized Berry phases for itinerant spin liquids
Quantized Berry phases as local order parameters in t-J models are studied. A texture pattern of the local order parameters is topologically stable due to the quantization of nonAbelian Berry phases defined by low-energy states below a spin gap, which exists in the large J/t case with a few electrons. We have confirmed that itinerant singlets in the wide class of t-J models carry the nontrivial...
متن کاملImaging Buried Interfacial Lattices with Quantized Electrons
We demonstrate that the well-known Sis111d-s7 3 7d superlattice buried under as much as 100 Å of crystalline Pb can be directly imaged with a scanning tunneling microscope at 77 K. The unexpected transparency of the metal and the high lateral resolution are the result of a nondiffractive scattering of the electrons at the interface. We attribute this phenomenon to a large anisotropy of the effe...
