Progress in performing angle-resolved photoemission spectroscopy (ARPES) with high
spatial resolution on the order of 1 lm or less (nanoARPES) has opened the possibility to …

Topological insulators are guaranteed to support metallic surface states on an insulating
bulk, and one should thus expect that the electronic transport in these materials is …

Substantial heterogeneity and defects in lithium-ion battery films can be a cause of material
and battery failure. Although non-uniformity has been observed previously, the physical …

Wearable electronics demonstrate great potential for a wide range of applications, including
electronic skin, implantable bio-medical devices, and health monitoring sensors. Such …

We show a new method to differentiate conductivities from the surface states and the
coexisting bulk states in topological insulators using a four-probe transport spectroscopy in a …

Electronic conductivity of battery electrodes and the interfacial resistance at the current
collector are key metrics affecting cell performance. However, in many cases they have not …

Low resistivity, near-surface do** in silicon represents a formidable challenge for both the
microelectronics industry and future quantum electronic devices. Here we employ an ultra …

Lithium-ion battery electrodes are generally made up of porous, thin films that are
structurally heterogeneous on multiple length scales due to the manufacturing process. This …

While it is known that the Si-(7× 7) is a conducting surface, measured conductivity values
differ by 7 orders of magnitude. Here we report a combined STM and transport method …

Thanks to advances in in situ measurement techniques for electrical transport in ultra-high
vacuum together with emergent materials such as Rashba-type surfaces, topological …
