Given equation:
x4+2x2+3x−2=0x^4 + 2x^2 + 3x - 2 = 0x4+2x2+3x−2=0Consider
f(x)=x4+2x2+3x−2f(x) = x^4 + 2x^2 + 3x - 2f(x)=x4+2x2+3x−2Signs of coefficients:
+, +, +, −+,\; +,\; +,\; -+,+,+,−Count sign changes:
+++ to +++ → No change
+++ to +++ → No change
+++ to −-− → 1 change
Therefore,
The most important semiconductor material is Silicon (Si).
Reasons:
Abundant and inexpensive
Forms high-quality SiO₂ oxide layer (essential for MOSFETs)
Good electrical properties (bandgap = 1.12 eV)
High thermal stability
Easy to purify and grow as single crystal
