Hai Semiconductor Devices is nothing but a device which conduct semi /partially conducting ( semiconductor which conduction property lies between conductor and insulator)is termed as semiconductor device.

Offcourse, that a semiconductor has a PN junction but that's not all the intrinisic property. Basically they are different in conduction property. these materials are not conductors by default they become conductors in some cicumstances like, increase in temperature or difference in the charge density, etc.
Germanium and silicon are the best examples of semiconductors...
there are three types of materials. they are conductor , semi conductor and insulator.
where the semi conductor lies between the other two. ie. controlled conduction is possible in semi conductor.
thats why it is preferred in electronic devices.
A PN junction is formed in all the three types of materials. but in semi consuctor the junction is very thin and easy to break it with the very low voltage.
