A novel structure of barrier controlled tunnel FET is proposed in the paper. The principles of gate work function engineering and channel doping engineering are combined to form up an in channel potential barrier, which can tune the source to drain tunnel current. The proposed structure serves as an alternative solution of barrier controlled tunnel FET fabrication, which combines the merits of the barrier controlled traditional MOSFET device and the bandgap controlled tunnel device. With carbon nanotube as the channel material, the device performance of the novel structure is verified using numerical simulation under the non-equilibrium Green’s function framework.

In order to search after a new way of the propulsion system of tracked vehicle, a novel structure form of electro-mechanical transmission was developed in this paper, through analyzing the advantages and disadvantages of existing projects of electric drive system for tracked vehicle. It could increase the rate of power exertion obviously and synthesize the mechanical and electrical strongpoint. And based on the structure form, an electro-mechanical transmission was designed with double electromotor added planetary mechanism of steering power coupling and gearshift, considering engineering realization. And then straight-line driving and steering performances of the transmission were calculated which proved that the novel electro-mechanical transmission could meet the requirement of tracked vehicle propulsion well.

A novel 4H-SiC MESFET was presented, and its direct current (DC), alternating current (AC) characteristics and power added efficiency (PAE) were studied. The novel structure improves the saturation current (Idsat) and transconductance (gm) by adding a heavily doped region, reduces the gate-source capacitance (Cgs) by adding a lightly doped region and improves the breakdown voltage (Vb) by embedding an insulated region (Si3N4). Compared to the double-recessed (DR) structure, the saturation current, the transconductance, the breakdown voltage, the maximum oscillation frequency (fmax), the maximum power added efficiency and the maximum theoretical output power density (Pmax) of the novel structure is increased by 24%, 21%, 9%, 11%, 14% and 34%, respectively. Therefore, the novel structure has excellent performance and has a broader application prospect than the double recessed structure.

Prussian blue analogue nickel ferrocyanide (NiPB) decorated carbon nanotube sponge (CNT sponge) was prepared as a newly designed spongiform adsorbent. This composite material was characterized by scanning electron microscopy (SEM), inductively coupled plasma (ICP) and tested in adsorption experiments. Results show that the CNT-NiPB sponge was equipped with large holes and porous structure, a large number of MWNTs and NiPB particles uniformly deposited on the surface and internal cavities. This adsorbent CNT-NiPB sponge showed a good adsorption selectivity of cesium and strontium in mixed aqueous solution, which is mainly induced by the ion exchange reaction of NiPB and metal ions. The novel spongiform adsorbent might have a promise prospect in radioactive wastewater treatment applications.

ABSTRACTIn this paper, a quantum-kinetic equivalent of Shockley-Read-Hall recombination is derived within the non-equilibrium Green's function formalism for a photovoltaic system with selectively contacted extended-state absorbers and a localized deep defect state in the energy gap. The novel approach is tested on a homogeneous bulk absorber and then applied to a thin film photo-diode with large built-in field in the defect-rich absorber region. While the quantum-kinetic treatment reproduces the semi-classical characteristics for a bulk absorber in quasi-equilibrium conditions, for which the latter picture is valid, it reveals in the thin film case non-classical characteristics of recombination enhanced by tunneling into field-induced sub-gap states.

This study discusses in depth about the moral values of responsibility in the novel Laskar Pelangi. Furthermore, the proposed related to the socio-cultural background of the authors in the creation of novel Laskar Pelangi effect on moral values. In addition, also discussed the author's view of the world related to the teachings of the value of responsibility. This research uses a qualitative approach with content analysis method. The results showed that the value of responsibility based on the novel structure consisting of man's relationship to himself, namely in terms of character and characterization. The characters are displayed Andrea Hirata bring the characters responsible for the thoughts, attitudes, and behavior. From a review of genetic structuralism, the value of responsibility based on social and cultural background, knowledge systems also influence the social and cultural life. Belitung people's livelihood systems are revealed also shape the character responsible. The author's world view of morals includes the value of self-existence, self-esteem, self-confidence, fear, longing, and responsibility.
