The structural, electronic, transport and optical properties of black phosphorus/MoS2 (BP/MoS2) van der Waals (vdw) heterostructure are investigated by using first principles calculations. The band gap of BP/MoS2 bilayer decreases with the applied normal compressive strain and a semiconductor-to-metal transition is observed when the applied strain is more than 0.85 Å. BP/MoS2 bilayer also exhib...

Semiconductor membrane fuel cells are a new promising R&D for solid oxide and proton ceramic cells. There is challenge of the electronic short circuit issue by using semiconductor to replace conventional electrolyte membrane. In this work, type II band alignment heterostructure based on Mg-doped ZnO can, one hand, block electrons passing through junction, other trigger ionic properties boos...

The features of the electroluminescence spectra narrow-gap type II InAs/InSb/InAs heterostructures containing a single layer InSb quantum dots placed into p-n-InAs junction were studied. luminescent properties under forward and reverse bias in temperature range 77–300 K investigated as function surface density nano-objects buried matrix. When applying to study, suppression negative interband lu...

background : diabetes mellitus is a metabolic disorder and is considered as the sixth most common cause of mortality. hospital readmission in patients with diabetes is important and can impose great costs on the health system. therefore, this study investigated factors affecting the readmission of patients with type ii diabetes to selected hospitals in kermanshah, iran, in 2012. methods: this w...

objective: studies reported conflicting results’ regarding the status of depression and glycemic control in patients with type ii diabetes(t2dm), therefore, this study was performed to determine the relationship between depression and glycemic control in t2dm patients. materials and methods: this cross-sectional study was performed on 150 t2dm patients referred to yazd diabetes research center,...

tyrosinemia type ii is a rare autosomal recessive disorder wich can present itself with recurrent epithelial keratitis, hyperkeratotic skin lesions and mental retardation. this article reports the rare occurrence of this disease in both offsprings (two brothers) of a family (consanguinous'marriage) who were managed with a lowprotein diet and a special regimen.

Blue phosphorene (BlueP) is a graphene-like phosphorus nanosheet which was synthesized very recently for the first time [Nano Lett., 2016, 16, 4903-4908]. The combination of electronic properties of two different two-dimensional materials in an ultrathin van der Waals (vdW) vertical heterostructure has been proved to be an effective approach to the design of novel electronic and optoelectronic ...
