Abstract

The optical properties of amorphous GaP (a-GaP) films prepared by plasma enhanced transport deposition method in the system of Ga-PCl3H2 have been studied. The optical energy band gap Egopt of a-GaP films is about 1.6 eV which depends on the contents of Cl atoms. The results of exponential absorption edge indicate that there is a high density of band-tail states in the optical energy band gap.

Abstract

A phototransistor of CE-PTHPT (punch-through heterojunction phototransistor with control electrode) with novel emitter control electrode and wide band gap emitter has been designed. The devices were working under the depletion on the base region. The base current is nearly zero and the output noise current decreases eventually so as to increase the optical gain greatly. There is an i type layer between the emitter and base region, low doped base region, implant isolated planar device and decreased emitter area in this device. The novel CE-PTHPT has been fabricated in this paper. The optical gain of GaAlAs/GaAs CE-PTHPT for the incident light power 1.3 and 43 nW with the wavelength of 0.8 /spl mu/m reached 1260 and 8108. The input noise current calculated is 3.7/spl times/10/sup -16/ A/H/sub Z//sup 1/2/. For polysilicon emitter CE-PTHPT, the optical gain is 3083 at the input power of 0.174 /spl mu/W. The optical gain of InGaAs/InP CE-PTHPT reaches 350 for an incident power of 0.3 /spl mu/W at the wavelength of 1.55 /spl mu/m.

Abstract

Objective: To evaluate the impact of preoperative dual antiplatelet therapy of aspirin and clopidogrel on perioperative blood loss and blood transfusion requirements., Methods: A total of 60 patients underwent off-pump coronary artery bypass grafting (OPCABG) performed by the same surgeons. And they were assigned to receive dual antiplatelet therapy of aspirin and clopidogrel (group AC, n = 30) and discontinue antiplatelet therapy more than 5 days before surgery (group control, n = 30)., Results: No significant inter-group differences existed in basic clinical characteristics (all P > 0.05). Itraoperative blood loss volume was similar for two groups (637 ± 257 vs 635 ± 196 ml, P = 0.978). No significant inter-group difference existed in 24 h chest drainage volume (522 ± 160 vs 524 ± 204 ml, P = 0.961) or total volume of chest drainage (1044 ± 337 vs 1118 ± 198 ml, P = 0.306)., Conclusion: Preoperative dual antiplatelet therapy of aspirin and clopidogrel does not increase the total volume of postoperative chest drainage.
