Anomalous thermoelectricity in strained Bi2Te3 films
Bi2Te3-based alloys have been intensively used for thermoelectric coolers and generators due to their high Seebeck coefficient S. So far, efforts to improve the S have been made mostly on changing the structures and components. Herein, we demonstrate an anomalous thermoelectricity in strained Bi2Te3 films, i.e., the value of S is obviously changed after reversing the direction of temperature gr...
متن کاملinvestigation of the electronic properties of carbon and iii-v nanotubes
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
15 صفحه اولsimulation and design of electronic processing circuit for restaurants e-procurement system
the poor orientation of the restaurants toward the information technology has yet many unsolved issues in regards to the customers. one of these problems which lead the appeal list of later, and have a negative impact on the prestige of the restaurant is the case when the later does not respond on time to the customers’ needs, and which causes their dissatisfaction. this issue is really sensiti...

Figure 1 . −K band structure evolution with T Si : a) 560 K (DP = 0.34 eV), b) 580 K (DP = 0.27 eV), c) 600 K (DP = 0.23 eV), d) 625 K (DP = 0.14 eV), and e) 630 K (DP = 0.12 eV). Upper panels show the ARPES intensity maps and lower panels show the corresponding MDC, measured at an interval of 10 meV. Red, purple, and green curves mark E F , VBM, and conduction band minimum (CBM), respectively....
متن کاملStrong Superconducting Proximity Effect in Pb-Bi2Te3 Hybrid Structures
To study the interface between a conventional superconductor and a topological insulator, we fabricated Pb-Bi(2)Te(3)-Pb lateral and sandwiched junctions, and performed electron transport measurements down to low temperatures. The results show that there is a strong superconducting proximity effect between Bi(2)Te(3) and Pb, as that a supercurrent can be established along the thickness directio...
