Study the Structural Properties of Porous Silicon and their Applications as Thermal Sensors
...Show More Authors

The photo-electrochemical etching (PECE) method has been utilized to create pSi samples on n-type silicon wafers (Si). Using the etching time 12 and 22 min while maintaining the other parameters 10 mA/cm2 current density and HF acid at 75% concentration.. The capacitance and resistance variation were studied as the temperature increased and decreased for prepared samples at frequencies 10 and 20 kHz. Using scanning electron microscopy (SEM), the bore width, depth, and porosity % were validated. The formation of porous silicon was confirmed by x-ray diffraction (XRD) patterns, the crystal size was decreased, and photoluminescence (PL) spectra revealed that the emission peaks were centered at 2q of 28.5619° and 28.7644° for etching time 12 and 22 min, respectively. Studying the capacitance and resistivity during temperature increasing and decreasing for both itching times shows clearly that the prepared pSi as a thermal sensor is working better and in more selectivity for 20 min itching time

There is no doubt that the narrative form is a mixture of many elements that it
becomes so hard to differentiate between them. Thus, to differentiate between those
elements we must understand the job of every element; and that is the structure of narrative
form in the artistic frame of the old Arabic poem.
Poetry, as the readers confirm, is strongly related to a lot of arts. The rhetorical
form is related to the art of drawing and photography, the rhythm- the core of poetry- is
related to music, its structure to the art of architecture, its tension to drama as it consist of
internal conflict between its elements and ingredients, and the poetry has a narrative
element which relates it to the art of narration and it

Each of the languages ​​possesses a set of phenomena that researchers in its sciences should stop at to explain the secrets of this language, including the phenomenon of idiomatic expression. Perhaps this phenomenon may constitute an obstacle to non-native speakers of the language or even the native speakers themselves. The Arabic language is full of these expressions, Which needs us to dedicate its own studies to it so that we can collect it in a dictionary that includes and collects it with explanation and interpretation of its semantics
