IET Digital Library: AlGaAs/GaAs tunnelling diode integrated with nanometre-scale oxides patterned by atomic force microscope
The authors have fabricated a tunnel diode comprising a two-dimensional electron gas channel formed at an AlGaAs/GaAs heterojunction by molecular beam epitaxy and nanometre-scale oxides locally generated using an atomic force microscope (AFM). The AFM-generated oxide lines have been adopted as integral parts of the device, for the first time serving as effective tunnel barriers for single electron transport.
Phys. Rev. Lett. 67, 516 (1991) - Coherent destruction of tunneling
The phenomenon of tunneling is investigated for a symmetric double-well potential perturbed by a monochromatic driving force. The analysis is based on a numerical treatment of the quantum map that propagates the system over one period of the external force, and of the spectrum of its eigenphases (quasienergies). The variety in the quasienergy spectrum, such as exact and avoided crossings, leads to novel forms of coherent tunneling. In particular, for specific parameter values of the driving force, we find almost complete localization of the wave packet in one of the wells.
Chemists observe “spooky” quantum tunneling | MIT News | Massachusetts Institute of Technology
Chemists at MIT and in South Korea have demonstrated characteristics of a phenomenon called quantum tunneling by using a very large electric field to alter the ability of ammonia molecules to switch between the normal and inverted states.
Automatic Tunneling and Encryption for Network Traffic | Community
Hello CommunityIs this procedure https://documentation.commvault.com/commvault/v11/article?p=129268.htm equivalent to using a network topology (network gateway for instance so that the traffic is tunneled through a single port 8403) and enabling the checkbox “encrypt network traffic” on the network...
Auto-Indexing Tunnels with For Loops and While Loops in LabVIEW - National Instruments
When wiring through a While Loop or For Loop, the tunnels for the wires are either solid or have square brackets on them. What is the difference between these tunnels? How can I change them? When wiring through a While Loop or For Loop, the data type entering is different than the data type exiting. Why is this?

Scattering and tunnelling: 5.2 Alpha decay - OpenLearn - Open University - SM358_1
Scattering is fundamental to almost everything we know about the world, such as why the sky is blue. Tunnelling is entirely quantum-mechanical and gives rise to such phenomena as nuclear fusion in...

Tunnel frequency dependence of the i.-r. continuous absorption and the proton dispersion forces - Transactions of the Faraday Society (RSC Publishing)
A continuous i.-r. absorption observed in solutions containing hydrogen bonds with symmetrical double minimum potential well may be due to tunnelling protons producing a fluctuating field causing attractive proton dispersion force. This decreases for tunnelling frequencies >5 × 10 s since the fluctuating dipole mom
