An amorphous semiconductor body, most advantageously a glow discharge deposited silicon-containing host matrix film, is provided containing at least fluorine as a compensating or altering agent, and most preferably at least one complementary compensating or altering agent, such as hydrogen, both of which reduce the localized defect states in the energy gap of the amorphous semiconductor.   One example is the crystallization of amorphous Si on rectangular glass substrates where crystallization during FLA starts at the hot corners. Even for a constant energy density, local variations of the material properties, in particular a variation of the reflectivity and absorption, will lead to pattern effects in temperature [ 62 ].Cited by:

Twenty-four years ago, Hellmut Fritzsche came to our laboratory to evaluate our work in amorphous materials. He came many times, sometimes bringing his violin to play with our youngest son, to talk, to help, to discover, and to teach. The times with him were always exciting and rewarding.

A peeling method is provided which does not cause damage to a layer to be peeled, and the method enables not only peeling of the layer to be peeled having a small area but also peeling of the entire layer to be peeled having a large area at a high yield. Further, there are provided a semiconductor device, which is reduced in weight through adhesion of the layer to be peeled to various base. Amorphous silicon (a-Si) and hydrogenated amorphous silicon (a-Si:H) are model amorphous covalent materials and are technologically important materials for photovoltaic applications [1]. The so-called second generation solar cells are constructed from a-Si thin films Ref. Sterling and Swann May.

Amorphous silicon (a-Si:H) is a very attractive material for large-area thin-film electronics, namely as thin-film transistors for flat panel displays, as color sensors, or as the absorbing layer for solar cells. The main advantages of this material are the low deposition temperature that offers the use of glass and flexible substrates, the potential for tuning the energy bandgap (– eV.

Proc. 2nd World Conference on Photovoltaic Solar Energy Conversion, Vienna () p. Google ScholarCited by: 2. A number of steady motes are in a high speed velocity, and collide with each other in all probability.

Stability is an important factor related to crystallization, which is generally a thermally activated process of transition from a disordered amorphous structure to an ordered crystal by: 2.

The process of crystallization in Zrat.%Fe amorphous alloy is of a polymorphic type in which the amorphous phase transforms without any change in composition to the Zr3Fe crystalline phase.

A way in which thin films of hydrogenated amorphous silicon (a-Si: H) can be instantaneously crystallized at room temperature is reported. The metal-induced solid-phase crystallization (MISPC. We have investigated the solid-phase crystallization (SPC) of hydrogenated amorphous silicon–germanium (a-Si 1−x Ge x: H) alloy films by using x-ray Cited by: 4.

In condensed matter physics and materials science, an amorphous (from the Greek a, without, morphé, shape, form) or non-crystalline solid is a solid that lacks the long-range order that is characteristic of a some older books, the term has been used synonymously with ys, "glassy solid" or "amorphous solid" is considered to be the overarching concept, and glass the more.

For one set of samples, hydrogenated amorphous silicon (a-Si:H) was sputtered on top of the Al without breaking the vacuum. For the second set, the samples were taken out of the vacuum chamber and exposed to the atmosphere to grow a very thin layer of native aluminum oxide before sputter depositing the a-Si:H.

Crystalline silicon (c-Si) is the crystalline forms of silicon, either polycrystalline silicon (poly-Si, consisting of small crystals), or monocrystalline silicon (mono-Si, a continuous crystal).Crystalline silicon is the dominant semiconducting material used in photovoltaic technology for the production of solar cells are assembled into solar panels as part of a photovoltaic.

In addition, it has been reported that nc-Si films pre- pared on Si wafers by metal-induced crystallization (MIC) of amorphous Si (a-Si) can be good candidates for seed lay- 2 Experimental procedure J.-H.

On the other hand, hydrogenated amorphous silicon (a-Si:H) has low μ because of carrier transport by hopping between localized tail-states [22,23].

Previous studies about TE materials as transparent conductive oxides (TCOs) were focused on correlation between figure of merit (ZT) and carrier concentration or a crystal by: 3. Mechanical, optical, magnetic and electronic properties of amorphous materials hold great promise towards current and emergent technologies.

We distinguish at least four categories of amorphous (glassy) materials: (i) metallic; (ii) thin films; (iii) organic and inorganic thermoplastics; and (iv) amorphous permanent networks.

Some fundamental questions about the atomic arrangements remain Cited by: The overall structure of the book has been changed slightly by distributing the material relating to amorphous metals throughout the text where appropriate, rather than including it in a separate chapter as in the previous edition.

A final chapter on some technological applications of amorphous materials has been added in its place. Abstract: It is necessary to improve the open circuit voltage of amorphous silicon solar cells for its applications. In this paper, we discuss the effects of hydrogen plasma treatment on the P layer and the performance of the amorphous silicon solar cells.

Amorphous chalcogenide semiconductor plays a key role in search for novel functional materials with excellent optical and electrical properties. The science of chalcogenide semiconductor (CS) show broad spectrum of soluble alloy and a wider band gap device that access the optimal energy bandgap.

The electronic properties of these alloys can be tuned by controlling the proportion of (S, Se, Te).Author: Mohsin Ganaie, Mohammad Zulfequar.
