Electron tunneling in MIS capacitors with the MBE-grown fluoride layers on Si(1 1 1) and Ge(1 1 1): Role of transverse momentum conservation

The current-voltage characteristics of the metal-insulator-semiconductor tunneling structures with calcium fluoride are simulated using different theoretical models. The results are compared to the data of current measurements on the fabricated capacitors with 1-3 nm epitaxial fluorides. Best agreement is achieved imposing a condition of transverse momentum k_⊥ conservation for a tunneling electron. This fact may be treated as an experimental proof for the k_⊥ conservation in the examined high-quality structures which was not directly confirmed on more traditional structures with oxide dielectrics.     

中东MIS构造Asmari组碳酸盐岩储层新认识

过去受技术条件、资料完整性及准确性等的限制,对中东MIS构造储层的认识存在一定的局限性。为此,根据最新的野外露头调查和新钻井获得的岩心普通薄片、铸体薄片、电镜扫描、CT扫描、EMI测井以及裂缝预测等成果资料,对该区Asmari组碳酸盐岩储层进行了深入研究与评价,获得了新的认识：①储层的主要岩性为早期白云化作用形成的细-粉晶白云岩岩类;②主要储集空间为晚期溶蚀作用形成的大量次生溶蚀孔、洞,白云岩类储层溶蚀孔、洞发育,物性好;③整体上,Asmari组上部基质储层在纵向上呈层状、多层叠置分布,横向上主要储层段具连续、连片分布的特征;④阿尔卑斯造山运动形成的构造张裂缝发育,主要为与构造走向（N45°W）一致的纵裂缝,在不同构造部位及不同层段,裂缝发育程度差异较大;⑤不同产状的构造裂缝组合构成了裂缝网络系统,裂缝与溶洞相互关联、配搭,形成了良好的缝-洞储渗系统,溶蚀孔、洞与构造裂缝配搭形成了良好的裂缝-孔（洞）隙型储层。

Direct Growth of Nanographene on Silicon with Thin Oxide Layer for High‐Performance Nanographene‐Oxide‐Silicon Diodes

Graphene‐silicon based configurations are attracting great attention for their potential application as electronics and optoelectronics. For their practical use, it is still limited by the configuration fabrication process. In this paper, a catalyst‐free method is reported to directly grow nanographene on silicon covered with a thin oxide layer to form nanographene‐oxide‐silicon configurations. Compared with previously reported nanographene‐silicon Schottky junctions, the nanographene‐oxide‐silicon structures exhibit a high performance on electronic and photovoltaic properties. The reverse leakage current of the nanographene‐oxide‐silicon is suppressed from over 10^?5 A down to 10^?8 A and the rectifier ratio is greatly enhanced from less than 5 up to 10³. The photovoltage is enhanced over 50 times. The nanographene‐oxide‐silicon structures exhibit especially ultrasensitive to weak light at a photovoltage working mode, which exceeds up to 10⁶ V/W at the light power of 0.025 μW. Due to the source material for nanographene is photoresist and the fabrication process is mainly based on the current‐used photolithography and silicon technique, the developed nanographene‐oxide‐silicon structures are very easy for device fabrication, integration, and miniaturization, and could be a promising way to produce metal‐free graphene‐silicon based electronics and optoelectronics for commercial use.
