Superconducting properties of Rh9In4S4 single crystals
The synthesis and crystallographic, thermodynamic, and transport properties of single crystalline Rh 9 In 4 S 4 were studied. The resistivity, magnetization, and specific heat measurements all clearly indicate bulk superconductivity with a critical temperature, T c ∼ 2.25 K. The Sommerfeld coefficient γ and the Debye temperature(Θ D) were found to be 34 mJ mol −1 K −2 and 217 K, respectively. T...
متن کاملSingle crystals of superconducting SmFeAsO1−xFy grown at high pressure
Single crystals of SmFeAsO1−xFy of a size up to 120 × 100 μm2 have been grown from NaCl/KCl flux at a pressure of 30 kbar and temperature of 1350–1450 ◦C using the cubic anvil high-pressure technique. The superconducting transition temperature of the obtained single crystals varies between 45 and 53 K. Obtained crystals are characterized by a full diamagnetic response in low magnetic fields and...
متن کاملEffect of impurities on the optical properties of KTP single crystals grown from flux
In the present work, KTP crystals have been grown by spontaneous nucleation technique in flux medium using K6P4O13 flux. 0.4-1 °C/h cooling rates were applied in the spontaneous nucleation process. The presence and amount of impurities has been determined by using XRF. The optical transmission spectra of impure KTP crystals in the UV–visible region are discussed. The transmission cut-off is cle...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولPhotoluminescence characteristics of Cd1-xMnxTe single crystals grown by the vertical Bridgman method
In this paper, we report a systematic investigation of band-edge photoluminescence for Cd1-xMnxTe crystals grown by the vertical Bridgman method. The near-band-edge emissions of neutral acceptor-bound excitons (labeled as L1) were systematically investigated as a function of temperature and of alloy composition. The parameters that describe the temperature variation of the energy were evaluated...
