The mechanical transistor, more properly called a nano-electromechanical systems transistor, creates and destroys the connection between source and drain mechanically.
机械晶体管,更确切地可以称之为纳米电子机械系统晶体管,它可以在源极和漏极之间机械地构建或消除连接。
When a voltage is applied across two beamlike electrodes made of aluminium, which areseparated by a gap of around 50 nanometres, charge builds up on each, creating anattractive force between them, until a critical point is reached.
两个柱状的铝电极间隔约50纳米,当电压加在这两个电极之间时,它们就会相互通电,在二者之间会形成一股引力,直至达到一个临界点。
At that moment one of the electrodes flips towards the other, causing the two to makecontact. This closes the circuit and turns the transistor on.
在达到临界点的那一刻,其中一个电极就会移向另一个电极,这两个电极就会形成通路。
Apply the opposite charge and the electrode flips back, breaking the circuit.
这样就会接通电路,打开晶体管。利用相反的电荷,电极就会复位,进而断开电路。
What makes these two very different types of transistor attractive is that both the copperand the aluminium stay put when the power is turned off.
