In practice, most organic conductors are doped oxidatively to give p-type materials. The redox doping of organic conductors is analogous to the doping of silicon semiconductors, whereby a small fraction of silicon atoms are replaced by electron-rich, e.g. , phosphorus , or electron-poor, e.g. , boron , atoms to create n-type and p-type ...
Organic CMOS logic circuit. Total thickness is less than 3 μm. Scale bar: 25 mm. Organic electronics is a field of materials science concerning the design, synthesis, characterization, and application of organic molecules or polymers that show desirable electronic properties such as conductivity.
Solid-phase proton conduction was first suggested by Alfred Rene Jean Paul Ubbelohde and S. E. Rogers. in 1950, [4] although electrolyte proton currents have been recognized since 1806. Proton conduction has also been observed in the new type of proton conductors for fuel cells – protic organic ionic plastic crystals (POIPCs), such as 1,2,4 ...
Transport phenomena have wide application. For example, in solid state physics, the motion and interaction of electrons, holes and phonons are studied under "transport phenomena". Another example is in biomedical engineering, where some transport phenomena of interest are thermoregulation, perfusion, and microfluidics.
Graphene is a semimetal whose conduction and valence bands meet at the Dirac points, which are six locations in momentum space, the vertices of its hexagonal Brillouin zone, divided into two non-equivalent sets of three points. The two sets are labeled K and K′. The sets give graphene a valley degeneracy of gv = 2.
In late July, Super Micro's auditor at the time, Ernst & Young (EY), raised concerns about the company's governance, transparency and internal control over financial reporting, prompting its board ...
The crowd-sourced fact-checking feature of Elon Musk's X, Community Notes, is "failing to counter false" claims about the US election, the Center for Countering Digital Hate (CCDH) said in a ...
There was hardly any movement at the top of the College Football Playoff rankings after Week 13.. The top four teams remained the same as Notre Dame moved up a spot to No. 5. The Fighting Irish ...
