CVD Grown Hybrid MoSe2–WSe2 Lateral/Vertical Heterostructures With Strong Interlayer Exciton Emission

Advanced Materials, EarlyView.
A scalable bottom‐up CVD methodology, based on liquid transition metal salt precursors, is presented for the controlled growth of two high‐quality MoSe2–WSe2 heterostructures (HSs): purely lateral (HS I) and hybrid lateral/vertical (HS II), by simply adjusting precursor concentration.

Establishing Atomic Coherence in Twisted Oxide Membranes Containing Volatile Elements

Advanced Materials, EarlyView.
Twisted oxide membranes containing volatile elements often suffer from amorphous interfacial dead layers that suppress coupling. An oxygen‐annealing strategy establishes atomically coherent and chemically bonded interfaces in twisted NaNbO3 membranes, enabling coherent oxide moiré architectures in volatile‐element‐containing systems.

Above Room Temperature Ferroelectricity in Epitaxially Strained KTaO3

Advanced Materials, EarlyView.
Through precise epitaxial engineering, the cubic and paraelectric KTaO3${\rm KTaO}_3$ is transformed into a robust ferroelectric. By leveraging lattice‐mismatched substrates to apply controlled epitaxial strain, a stable ferroelectric ground‐state is achieved with a transition temperature as high as 475 K, establishing KTaO3${\rm KTaO}_3$ as a highly ...

Engineering the Assembly Freedom of Donor–Acceptor Type Self‐Assembled Monolayers Toward Efficient and Stable Flexible Perovskite Photovoltaics

Advanced Materials, EarlyView.
Assembly freedom engineering breaks the vertical alignment constraint of donor–acceptor self‐assembled monolayers, tuning their assembly freedom to achieve quasi‐random molecular orientation. This strategy simultaneously boosts interfacial charge transport and mechanical robustness, enabling high‐efficiency and mechanically stable flexible perovskite ...

Quantum Chaos, Transport, and Control—in Quantum Optics

2006
Chaos implies unpredictability, fluctuations, and the need for statistical modelling. Quantum optics has developed into one of the most advanced subdisciplines of modern physics in terms of the control of matter on a microscopic scale, and, in particular, of isolated, single quantum objects.

Quantum Transport

2009
Quantum transport is a diverse field, sometimes combining seemingly contradicting concepts - quantum and classical, conduction and insulating - within a single nanodevice. Quantum transport is an essential and challenging part of nanoscience, and understanding its concepts and methods is vital to the successful fabrication of devices at the nanoscale ...

Quantum Transport and Quantum Pumping

2018
The usual laws of the circuits (Ohm’s law, Kirchoff’s law, and so on) are valid in the macroscopic world. However, when the linear dimensions are less than an electron mean free path, which may be on the order of 10 nm (22 in Al and 55 in Cu), the motion of the electrons is ballistic, that is, the circuit obeys quantum laws.

Quantum transport through an array of quantum dots

Nanoscale, 2013
The transient current through an array of as many as 1000 quantum dots is simulated with two newly developed quantum mechanical methods. To our surprise, upon switching on the bias voltage, the current increases linearly with time before reaching its steady state value.
