Molecular crystals from thiophene molecules can be doped with TCNQ-F4 molecules for use in all-organic optoelectronic and semiconductor devices. The charge transfer and the molecular orbital energy level formation in between these two organic molecules are investigated here by density functional theory calculations. The isolated molecules are calculated nonbonded and bonded together, forming a ...

Quantum phase transition achieved by fine tuning the continuous phase transition down to zero kelvin is a challenge for solid state science. Critical phenomena distinct from the effects of thermal fluctuations can materialize when the electronic, structural or magnetic long-range order is perturbed by quantum fluctuations between degenerate ground states. Here we have developed chemically pure ...

Courses on Machine Translation MT need to be tailored to di erent sets of students with di ering skills and demands Kenny Way Nevertheless any contemporary course on MT ought to equip students with at least a super cial knowledge of the di erences between rule based and statistical MT direct and indirect approaches and transfer based and interlingual systems With regard to this latter distincti...
