Feasibility Study of Direct Measurement of Stellar Reaction 22Mg(α,p)25Al
Communications in Physics - Tập 21 Số 2 - Trang 169 - 2011
Nguyen Ngoc Duy, Le Hong Khiem
The stellar reaction 22Mg(α,p)25Al plays an important role for understanding the nucleosynthesis of stars. It has never investigated yet. We are planning to study this reaction in environment of X-rays burst with temperature T9 = 1÷3 GK using invert kinematics and thick target method. This paper shows a design for direct investigation of this reaction by simulation method. This design is necessary... hiện toàn bộ

Investigation of Energy Transfer in a Blend of electroluminescent Conducting Polymers
Communications in Physics - Tập 21 Số 4 - Trang 373 - 2012
Nguyen Nang Dinh, Nguyen Phuong Hoai Nam, Do Ngoc Chung
With the aim of improving the photonic efficiency of an organic light emitting diode a blend of electroluminescent polymers, poly[9-vinylcarbarzole] (PVK) and poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) was prepared. The energy transfer in the blend was investigated through the comparison of absorption, photoluminescence (PL) and current-voltage (I-V) characteristics of the... hiện toàn bộ

Measurement of the Yield Ratio of the \(^{122m,g}\text{Sb}\) Isomeric Pair Above the Giant Resonance
Communications in Physics - Tập 22 Số 1 - Trang 75-81 - 2012
Pham Duc Khue, Kim Tien Thanh, Nguyen Van Do
The yield ratio of the high-spin state of \(^{122m}\text{Sb} (8^{ - })\) and the low-spin state of \(^{122g}\text{Sb} (2^{-})\) formed via the \(^{123}\text{Sb}(\gamma, n)^{122m,g}\text{Sb}\)  reaction has been measured as a function of the bremsstrahlung end-point energy in the range of 40-MeV to 60-MeV. Use was made of the activation technique in combination with high-resolution \(\gamma\)-ray s... hiện toàn bộ

Germanium Band Gap Engineering Induced by Tensile Strain for Si-Based Optoelectronic Applications
Communications in Physics - Tập 23 Số 4 - Trang 367 - 2014
Luong Thi Kim Phuong, Nguyen Manh An
We have combined structural and optical characterizations to investigate the tensile-strained state and the band gap engineering of Ge layers grown on Si(001) using molecular beam epitaxy. The tensile strain is generated in the Ge layers due to a difference of thermal expansion coefficients between Ge and Si. The Ge growth on Si(001) was proceeded using a two-step growth process: a low-temperature... hiện toàn bộ
