Thermionic Emission
The cathode space charge is determined by the voltage on the filament.
The space charge region in a pn junction at equilibrium is often made small due to:to obtain a high junction capacitance;since the junction capacitance is inversely proportional to the width of the space charge region, the smaller the width, the larger the junction capacitance.to ensure easy diffusion of charge carriers;if the space charge region is made small, that is, the width is made small, the distance for diffusion also becomes short, then it becomes easy for the electrons to diffuse into the p-side and the holes into the n-side
Water overflows when you put something in it due to the principle of displacement. When an object is submerged in water, it pushes aside a volume of water equal to the volume of the object that is submerged. If the volume of the object exceeds the remaining space in the container, the water will spill over the edges. This is a demonstration of Archimedes' principle, which states that the buoyant force on an object is equal to the weight of the fluid it displaces.

Radio is the transmission of signals, by modulation of electromagnetic waves with frequencies below those of visible light. Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space.

Space is made of mass and charge.
The influence extended to a surrounding space by a charge in motion is the gravitational field.

The cathode space charge is determined by the voltage on the filament.
In a semiconductor, the charge concentrates at the bounds of the space charge region(depletion layer).
