The Hamiltonian size reduction method or the mode space applicable to general heterogeneous structures is developed in this work. effectiveness and accuracy of are demonstrated for four example devices GaSb/InAs tunnel field effect transistor (FET), MoTe2/SnS2 bilayer vertical FET, InAs nanowire FET with a defect, Si rough surfaces. reduced around 5 % original full without losing calculated tra...

distributed sensings on temperature and strain have been extensively investigated based on Raman [1] and Brillouin [2] scattering methods, respectively. During the course of our developments on a new sensor which can work as one of sensing elements for multi-point detection using a Rayleighscattering based OTDR through an optical fiber network, a hetero-core fiber optic sensor was exploratively...

Melanins, the ubiquitous hetero-polymer pigments found widely dispersed among various life forms, are usually dark brown/black in colour. Although melanins have variety of biological functions, including protection against ultraviolet radiation of sunlight and are used in medicine, cosmetics, extraction of melanin from the animal and plant kingdoms is not an easy task. Using complementary physi...

The utilization of Pd nanoparticles stabilized by aggregates of hetero-oligophenylene derivative 3 as an excellent catalyst in a copper/amine free Sonogashira coupling reaction under aerial conditions at room temperature has been demonstrated.

A DNA duplex was used as a scaffold to evaluate the intrinsic reactivity of [2 + 2] photodimerization between stilbene derivatives; the duplex pre-organizes the substrates avoiding the need for an association step. Unmodified stilbenes were first introduced at base-pairing positions on complementary DNA strands. The duplex was then irradiated with 340 nm UV light. HPLC analyses revealed that [2...

The first total synthesis of (+)-cytosporolide A was achieved by a biomimetic hetero-Diels-Alder reaction of (-)-fuscoatrol A with o-quinone methide generated from (+)-CJ-12,373. The dienophile, highly oxygenated caryophyllene sesquiterpenoid (-)-fuscoatrol A, was synthesized from the synthetic intermediate in our previous total synthesis of (+)-pestalotiopsin A. The o-quinone methide precursor...

To meet the performance requirements of low power mobile devices, a device with high ION/IOFF ratio at low-VDD is needed. TFETs are gaining popularity due to their subthreshold slope and transconductance compared MOSFETs. However, silicon-based have on-state current, which limits use in high-performance applications. overcome this limitation, using narrower band gap material like Ge can increas...

Abstract The electronic properties of tetragonal BiFeO 3 based hetero-structures, along with the phase SrTiO and PbTiO in (001) direction, is investigated two types interfaces. In case /SrTiO hetero-structure, (FeO 2 ) − /(SrO) 0 , (BiO) + /(TiO interfaces are respectively. For /PbTiO /(PbO) / (TiO studied. A tiny amount half-metallicity has been found interface while behaves as metallic hetero...
